How To Combine Two TV Antennas for More Channels

[@AntennaMan]

❗ MAKE SURE TO WATCH MY UPDATED VIDEO ON THIS TOPIC BELOW 📺 kzbin.info/www/bejne/b2KUaXutbdyNfqM UPDATE: Since I made this video Televes released an antenna combiner linked below that will not negatively impact reception: amzn.to/3zpj2XC

[@lisaa1134]

Sorry placed answer separate. Both reception problems just can only get channel 12 in bedroom which is 12.1,12.2,12.3,12.4,12.5,12.6. Living Room receives that & 5 different channels plus the extras for all the channels without turning antenna so no there is no reception problem has to be in house.

[@lisaa1134]

Could the cable be the issue? If it could be why are we receiving the one channel? I think this is why I am stumped.

There is a good way to combine different antennas without causing any interference, hook up each antenna to it's own HDHOMERUN device. Many smart TVs now have the HDHOMERUN app.

Hey Antenna Man love your reviews i’ve been getting over the air service since 2006 witch includes the conversion from analog to digital. Two years ago I started losing two stations.... I’m in 05356 at an altitude of 2000’ and pick up stations from Albany N.Y. my antenna faces south west I pick up NBC Fox WGBY and CBS but it constantly pixelates and drops out.... any suggestions. I have a Winegard 8700u and a Titan 7777 Pre-amp.

Two network TV tuners (ie: Hdhomerun), each one connecting to a different antenna, which will be facing a different directions. This way all device on your network gets all channels.

You are brilliant sir! Your solution is definitely another (albeit slightly more costly) solution. I’ve got one (hdhomerun dms 10631cca) and have it running thru my Plex server. Great little device!

[@ElectricBobber]

I just installed and am using a Winegard CC-7870 Antenna Coupler I bought on Amazon. Its doing a great job of interfacing my Clearstream 2V antenna facing northwest (that I am using for UHF channels in my area), and a homemade VHF Single Dipole antenna facing southeast tuned for channel 11 (28.1 inches in length, other VHF channels would benefit from their own calculated length). FULL DISCLOSER: The two antennas are shielded from each other and their signal direction by a distance of about 30 feet by using the house itself to isolate them, and then each antenna has a long run of RG6 Coax to the inside of the house where I am using the Winegard Combiner. Using a signal strength meter I have only noticed a 2-4% loss using this device, well tolerated for what its doing for me. Thank you Antenna Man for the wonderful and informative videos you have made. They have really helped us out here trying to cut the cord.

[@manfredcaranci6234]

Antenna Man, you have an amazing and uncanny ability to convey realistic, practical, and just plain common-sense information about HDTV reception via antennas. A potential "cut-the-cable" devotee should be required to watch a few of your videos so (s)he would understand that you cannot pick up signals that just aren't there, no matter where you put an antenna or how much amplification you use. Well done! Please keep up the fine work.

[@ke2dk]

I am a extra class amateur radio operator and I have a pair of 2 meter Yagi antennas phased together on a pole with a rotator. that work exceptionally well. At first after i built these antennas, both identical, they would not load up properly at all. Then an old timer ham told me to turn the top one bottom side up . He said that one antenna was cancelling the other out. I did as I was told and they load perfectly and have worked for twenty years. I must add that I was using these antennas for transmitting so it might not make a difference for receiving.

[@jenko701]

The way to do it is with microwave filters it’s what I do at a large hospital. I have two antennas. One gets the majority of channels, the other gets the one channel that’s in a different direction. Each channel gets it own microwave filter for the actual RF frequency of the station then I combine them with a RF splitter and send it to a amp for distribution. The problem is it’s not practical for the home owner to do this because of cost. Love your channel you are right on the money with your information.

[@electronron1]

Back in the 70's I used to install antennas and we used what was called and area special which consisted of 4 antennas connected in a particular order using 300 ohm twin lead, that was supplied with the antennas, that were pre-cut to specific lengths. These antennas allowed every TV in the house to receive any channel and no rotor required. They worked great. If I recall they were made by Winegard.

[@5argetech56]

I really hear you on that one. I had to move my antenna around five times until I finally found the sweet spot. That receives about 32 channels clearly all day.

[@rjskoko]

I am successfully combining signals from two antennas mounted in my attic. I am about 15 miles from one set of broadcast towers and 35 from another cluster. I believe that there is a key point to maximize the chance for getting a good result: Try to have the two antennas pointed in directions 90 degrees apart. This puts the main "beam" of one antenna in the "null" of the other. I am fortunate that in my situation that arrangement matches the compass directions of the two transmit antenna clusters.

[@STBRetired1]

Good point, I'll give that a try.

[@dennisgarber]

This totally makes sense! I wonder if it usually always works in practice, with the expected exceptions, or always.

[@RichardSkokowski]

@@dennisgarber I would expect the results to depend very much on the actual side lobes of the two antennas being combined. My pair of antennas happen to work well (and have for 26 years now). I oriented each antenna in isolation for "their" set of channels before combining them, so I suppose that might be a good practice.

[@revdamonaconn7387]

Very good about explaining the ghosts effect. I combine two antennas and I received extra channels. ( using vertical and horizontal antenna) You mention about grounding. I completely ground everything and I gained a total of 13 extra channels. Given me a total of 43 channels. But I need to add that my antennas are on top of my 108 foot Tower that I used for my amateur radio. Thank you for keeping it real Rev Damon A Conn

[@jameskeefe1761]

You can combine antennas, different metro areas would have "area specials" where the antennas were configured properly with each other. One was Tampa Bay Special for instance for Tampa, since WTSP used to be located in Holiday, FL, while the rest are in Riverview, so WTSP got its own antenna.

If you have the right gear you can use an RF signal generator and a scope to precisely adjust the length of the two coax feeds to perfectly overlap the two signals. This is a major pain and won't help for reflection issues. i.e. if the multipath is somewhat unstable. Good chance you'll end up with a pile of extra coax on one of the feeds. Not the only way, but one way.

[@AntennaMan]

Yes, I've been told that's the trick.

[@dennisgarber]

This claim that matching identical antenna, identical cables, identical spots, and different directions, is something that needs to be tested like myth busters! Not only as to whether it works, but if any one or 2 of the 3 variables make a huge or small difference. I just bought a $79 Televes 560483 It worked great to combine a large attic antenna with an outside art piece antenna pointing 30 degrees apart. The televes balanced the signals and added them. No evidence of multipath. So, naturally, I am wondering if I wasted money. Most likely in my case I did not, because I was forced to use 2 antenna. I am also wondering if 30 degrees is not enough to create multipath or I got lucky, or if the tuners I tested or televes eliminated the multipath.

[@crashbang7217]

What would happen if you pointed identical antennas at the same tower and joined them with a combiner would the signal go up or would that cause issue. Gonna be an attic setup

[@skcyclist]

Thank you for information. I have two antennas facing opposite directions. One toward Santa Barbara (west) local, the other toward L.A. (east) distance. Both have preamps. I have the splitter mentioned to switch between antennas. Only glitch is the TV set must be auto programmed for each antenna. Can't simply flip the antenna switch and expect the former programming to work. I'm still experimenting which is kind of fun. I'm 76 years old and when I was a young teen, my Dad and I loved to mess with crystal sets and antennas. BTW my antenna mount is about 8 feet above the roof line and I think I better run a guy wire as it's kind of shaky. Also couldn't drill through (tough mount) where they overlap to install a screw, so I spliced them together with one of the antenna mounts. Call it semi-stable.

[@AntennaMan]

You might benefit from this video. With the DTV box I use you can manually add channels so you wouldn't have to run rescans when changing direction. kzbin.info/www/bejne/rpisop5uhd5mfMU

Putting two antennas together gives you a lot more gain.Add a pre amp and pick up alot more channels.

[@jeffm2787]

Only if you can get the phase of the two exactly right. Lots of coax length tweaking. They may still sell variable delays for this purpose which allow for fraction of a picosecond delay changes. More or less a trombone type device inside a sealed can which changes the length of the signal path via a mechanical adjustment. Not cheap.

[@berfunkle4588]

All of my in market channels are UHF, but there are some out of market channels I would love to have that are high VHF. Glad there's a straight forward solution to this by using a VHF/UHF combiner. Also, that Stellar labs high VHF antenna model you reviewed seems like it will do the trick for tramsnitters about 50 miles away with no mountains in between.

[@scharkalvin]

Also add notch filters to remove the signal from the antenna in the wrong direction for each channel that is lost to multipath.

[@robertgrlic6505]

[@TheJTcreate]

@@burblegobble Notch filters should still have been covered.

[@miguelangeloconceicao738]

When combining 2 antennas (or any RF source for that matter) in the same frequency band with a simple RF combiner/splitter you have to make sure that both input signals have more or less the same Amplitude levels, otherwise the sideband of RF carriers on the stronger input will end up overlapping the adjacent RF carriers on the weaker input sinal. Try attenuating the stronger signal to the same amplitude level of the weaker signal before combining both. The resulting/combined signal can then be amplified

[@Pidalin]

when you just connect 2 antennas together without channel filters, you literally create 360° antenna, which is obviously bad idea

[@miguelangeloconceicao738]

@@Pidalin That's correct. If you want to combine specific channels from antenna A with other specific channels on antena B, you should filter-out the unwanted/duplicate channels on both antenas (meaning, on Antenna A you should filter-out the channels that are already being picked up fine by Antenna B, and vice versa) - otherwise you will get multipath interference on the combined RF coaxial

[@Pidalin]

@@miguelangeloconceicao738 It worked for me for some time when I was catching one multiplex with vertical polarization and rest of programs with standard horizontal polarization, when you have antenna in vertical polarization and there is only one transmitter with such polarization around, then you can just connect antennas together, horizontaly polarized signal is very weak on verticaly oriented antenna. We have transmitters with vertical polarisation only in two biggest cities which is like 200 km from each other so there is no interference. I heard that Slovaks changed all their transmitters to vertical polarisation for some reason, I guess such little country has problem with interferences from other countries, so that could be solution. We also have (here in Czechia) some problems with Polish transmitters, they have 100 kW transmitters literally on our border which is not kind from them, but it's good for people who like to catch foreign TV. Unfortunately Germans and Austrians made all transmitters very directional when they changed to DVB-T2 so catching their TV is almost imposibble now, but it solved interferences from their channels.

Not all have luck with multiple dipoles, although it's worth a try. I happened to luck out: built a Gray-Hoverman antenna with no reflector. So I pull in channels from both Needham and Springfield, opposite directions --> same antenna. This is possible only because digital broadcasts have error-correction. 13 years ago my setup would not have worked out. Going to be interesting through the repack of course, since the two markets are in repack phases 4 and 8. I may lose some channels, and maybe gain one or two. I'll definitely lose the channel moving to low-VHF.

There are 2 LP FM radio stations in top of that mountain. I have my antenna pointed straight at that mountain and I get all the Chattanooga Stations, all but one of the Knoxville stations (and nothing is on that channel I want to watch anyway) and one PBS affiliate from Atlanta, GA.

[@starroger]

I have two UHF only antennas pointed about 100º apart plus a long range VHF only antenna pointing about 180º from one of the UHF antennas. Each channel I pick up is a different frequency, so no multichannel interference for me. I combine all three antennas with a Televes three antenna combiner that comes with a two port power inserter/distribution amplifier. The cool thing about the Televes combiner is that you can adjust the gain for each antenna separately. That comes in handy because one of the UHF antennas has a long cable run before it gets to the combiner. This antenna has a Channel Master pre-amp. I dial down the gain on the combiner for this antenna so as not to over amplify the signal going to the TV. Finally I use quad shielded RG6 cable to maximize signal transmission and minimize interference. This presents a slight problem with the combiner as it is not designed for the extra thickness of quad cable. However, it was fairly easy to modify the the way the quad cable is fed into the combiner. Over all, I am very happy with the way this system works.

[@dennisgarber]

You bought the televes smart Kom 3 years ago. Is it still working well?

[@starroger]

@@dennisgarberYes. As of last summer (2023) , I was able to pick up adequate signal from Vancouver BC (100 miles) on the UHF antennas, and Seattle (60 miles) on the VHF antenna. My modifications to accommodate the quad coax cable was to replace the stock clamps with large fender washers, which I filed to fit the space for the cable attachments. The newest Televes combiner has female F connector points. My modifications are not nesessary for this newest version.

[@allanpatterson7653]

In the NTSC days I would put tunable traps on antennas as each station was a different strength and direction. I took the local station which was blasting away from 6 miles away took an antenna tuned to its wavelength pointed directly at it and then attenuated it by 100db it was a perfect signal as it also knocked down the noise by 100db. The other channels were all filtered and levelled. Nowadays with the ATSC system ghosting is not that big of an issue. I know a fellow living in an apartment building and his balcony faced the wrong way to point an antenna in the direction to get his favorite station. He managed to get the signal by pointing antenna at another building an caught a reflection. ATSC aeems immune to ghosting.

[@rickw3785]

If you are going to use a "splitter backwards" you have to make sure: 1st, that the lengths of cable between the antenna and the splitter are exactly the same. 2nd, space the antennas a few feet apart so that they don't interfere with each other, 3rd, Use the same model antenna before combing..... Otherwise, you are absolutely certain to have ghosting or multipath issues. 📶

[@urself25]

Ghosting in the analog days was due to signal echo mostly because each signal arrived with a slight time delay. To be able to use both antennas, you need to have both antennas on the same pole with both antennas connected to the same plexer by 2 cable of the same lentgh this way, even though the antennas not facing the right direction stil get the signal, it is transported down the cable at the same time and speed as the other antenna.

[@royshashibrock3990]

The author gives some good info, but I would like to clarify a few things. Regardless of whether the signal is digital or analog, ghosting is caused by the reception of two out-of-phase signals. If a signal reflects off of a nearby tree, for example, this reflected signal will in turn recombine with the signal that reached the antenna by line of sight when it arrives at the antenna. The reflected signal has a longer path to travel, hence the out of phase reception. In the author's example, he mentions the two antennas being at right angles from each other, and if he has nearby trees or buildings, it is entirely plausible that this caused the out of phase condition. In any case, it is NOT the mere fact that two antennas are combined that is causing the problem, as long as they are equidistant from the station (read: mounted on a common mast). The same problem would be created if you use two different lengths of cable from the two antennas to the combiner. Combiners/splitters are lossy things, and you will lose at least HALF your signal power using them. The better choice (if you can find one) is a two-input signal amplifier. I have had great success combining a Stealth Hawk antenna with no reflector (receives on both broad faces - google it) for the direction(s) with nearer/stronger stations, and on the same mast, but 90 degrees rotated, a Gray Hoverman with no reflector (receives on both broad faces - google it) for the more distant/weaker stations. These are both designs available on the web to make your own antenna. I use a combiner with equal length feeder cables for now; but I am looking for a two input amplifier (I may build my own). BTW, who wants to waste time with an antenna rotation drive?

A bi-directional broadband splitter can be used to combine the received signal from two antennas with the use of quality custom notch filters between each antenna and the splitter. We use them in the amateur radio and scanner world all the time for frequency isolation. You can purchase one or make one yourself. The frequency formulas can be found on the web.

I'm gonna have to do something like that soon. In my area, all of my TV channels were broadcasting from towers in the same general direction, but there's one station I watched a lot that moved the signal to halfway opposite direction of where my antenna is pointing at and therefore can no longer be picked up by that one antenna I have. Luckily I have some spare quality antennas laying around at home, so all I really need to do next is to get the splitter and perhaps some more knowledge on how to do this.

[@22bungalow]

Great vid, very informative. What if you have 2 markets in opposite directions and you use highly directional antennas, could that work to cut-out multipath? Is there any way to shield an antenna to make it even more directional, i.e. antenna blinders? maybe faraday shielding? Let's assume they both have vhf/uhf so first option is not possible.

[@pablopicaro7649]

great info, what about the Winegard CC-7870 (or similar) it might be hard to find any more.

[@elianetuyipfukamire4392]

Thanks man...I had no idea about multipath interference, now I know...

[@bloqk16]

(in a tone of astonished enlightenment) Aaahhh! So the multipath issue may explain why my two receiving antenna array in my attic blocks out digital channels 29 and 40, while digital channel 2 comes in fine. My attic antennas array consists of a CM-4228HD; with the digital channel 2 reception coming from a V shaped homemade antenna made out of PVC pipe. The recommendation, in this video, of UHF/VHF combiner may be the solution to the reception issue I have. In another video post comment, by Tyler GH, it was suggested to me about a cm3020 antenna to resolve the lo-VHF/high-VHF/UHF reception issue. I attempted that antenna attic install years ago, but the roof rafters extremely restricted its lateral movement of that antenna when it came to adjustments; where I could not receiving the low-VHF digital channels; so I scrapped that ChannelMaster antenna. Although in my HOA restricted community I can install an outdoor antenna, the issues with summer lightening storms, the gale-force winds from the thunderstorm micro-bursts, and the lack of confidence with local installers not to damage the roof or siding of the house with the antenna installation, discourages me from going to an outdoor install. Where I live, the selection of (ahem!) "professional" installers is slim, and I've heard about their handiwork on houses in my community. In addition, I'm at an age where climbing a 25 foot ladder, to reach the roof for a do-it-yourself antenna install, is not in the cards with me.

[@MrBOB39]

I hear you on the Not at age or desire to go up on roof or in the attic to do the install.. However.. Try looking up in your local area for ham radio operators... they are Expert in all aspects of needed antennas..coax feedlines..if needed using antenna pre-amp and or signal blaster within your home and far more

[@Clifford1966]

I tried to connect 2 power antennas to the splitter. This didn't work. I found out that you have to use a bi-directional splitter. Like this one, Channel Plus 2512 DC/IR Passing Splitter/Combiner, 2-Way

[@patriciamomney8373]

Awesome stuff! You were right about the cable being bad, thanks!

[@MarvelDcImage]

using a seperate tune box for different facing antenna connected to its own hdmi input gets this done for me. I am not combining signals just seperate antennas for each tuner box.

[@AntennaMan]

Yes, this is a good solution I'll mention in an updated version of this video soon.

[@scottlarson1548]

In the old days we had "channel traps" which were just filters for specific channels. We had one antenna for channel 4 going through a channel 4 trap, an antenna for channel 6 going through a channel 6 trap, and a third antenna for the rest of the channels, These were combined on the antenna and then went down through the old 300 ohm twin lead to our television. *Everyone* in our area had multiple antennas on their roofs. There was simply no other way to get all of the channels except using a rotor which I don't recall anyone using.

[@shawnhiemstra7990]

Back 10 -15 years ago you could buy those traps from ChannelMaster, they were called JoinTenna. But they've replaced that product like now with a new "JoinTenna" that apparently does the notching automagically. I would consider this a 4th option.

[@wilywood]

This is super helpful. I am not that far away, in central NJ, and have the problem that markets are basically 1/2 NYC (to the north) and 1/2 Philly (to the south) and each a mix of VHF/UHF. My house is oriented East-West under a metal roof with one area on the east-side of the attic (a small, hard-to-access chamber) to install antennas. So I have to aim antennas through the wall near the peak of the roof. I installed two within a few feet of each other, one pointed NE and the other pointed SE (hoping to grab signals from Philly and NYC), using two of the same model UHF/VHF antennas and equal lengths of cable connected to a passive splitter. I lost half my channels by connecting the second antenna. Surely this is related to interference as nothing else changed. The question is whether there is a powered device that can merge and resolve the signals? Is the situation hopeless? If anyone could help that would be great.

[@AntennaMan]

No power will only make the multipath interference worse. One option you can do is run two cable lines. Connect one to your TV directly and the other to a Tablo or AirTV and access the different market stations that way. If you need assistance I do service your area. My website is antennamanpa.com

[@jatrippe77]

Thank you for the video. I’ve got a multi directional antenna that I have pretty high up in my attic right now it gets great signal strength Except for there’s this one channel that has a lot of pixelation. I was thinking of adding a directional antenna to pick up the One channel that is having issues. It is in a slightly different direction than all the other channels. I will use all cables that are exactly the same brand type in length. I have a channel plus signal combiner that allows for DC circuits to pass. I also have a preamp on the antenna I currently have. Should I leave the preamp on the one antenna or can I install the preamp after the combiner? Also, do you think a directional antenna is good to add a system to help pick up a channel that’s a little weaker than the others?

[@jeffarthur322]

Thanks, actually knew most of what you stated. Been messing with antennas over 50 years. It’s odd that after all that time that reception still works pretty much the same

[@rickbro5949]

My solution involved separate antenna cables,one to the tv antenna input the other to a hdmi tv tuner (mediasonic) to the hdmi input of the tv.Toggle on the remote input button to switch antennas.Remote convenience and eliminating some of the problems like rescanning ,filters,,multi path.abs switch wear and the separate tuner might improve the reception signal.

[@TheZehnerhjk]

Having a triangl tower I would like to have three separate antennas. How would one hook these together, using one coax to television?

[@AntennaMan]

You'll probably kill your signal if you connect all three together. Maybe two combined and an A/B switcher.

[@jC-kc4si]

Setup 3 tv's each with their own antenna. In the 80s an evening magazine news story showed a family of 'couch potatoes' who had 5 or more tv's that they watched all at the same time. Maybe I can find that video on KZbin.

[@RazorStrap]

Could feed each antenna into a separate networked tuner and set the display device to use the tuner based on channel. No combiner used this way and mismatched coax not an issue.

[@cynthiamateo9450]

Love your channel. You helped me out so much.

[@campshortclip]

I thank you for your videos. Before i found your channel. I purchased that directional that you dont recommend. But i have it outside. Just above my roofline. Scanned and got 29 channels.

[@Chris-dn9cq]

I have had two of those it does work good I get 59 channels but the cable connection at the base broke and the rotator and the other one the cable connection broke off on the amplifier box 🤦

[@pcno2832]

I've seen remote-controlled A-B switches on various shopping sites; I expect to try one out. You could also aim the attic or outdoor antenna for the direction of the weakest stations and have a hand A-B switch and a bow-tie aimed in the direction of the strongest ones near each set. The idea would be a phased array that automatically selects the strongest direction for each channel and puts them all on the wire; I would think something like that would be a necessity for a large building with lots of users dependent on one antenna system.

[@AntennaMan]

I'll look into a remote A-B switch

[@jC-kc4si]

That's fine when you are watching real time tv. Your antenna DVR will not be able to switch from a to b when it's recording shows when you are away from home or sleeping.

[@denniskingsley1485]

Interesting.... I hav an indoor multi directional antenna covered in plastic. Other antenna is pointed towards RAL N.C with a basic splitter. Total channels, 53 ... long distance antenna I purchased from Ollie's for 20.00

[@MatHelm]

I think your problem is signal attenuation, because of (mostly) different lengths of cable from your antennas to your splitter. But also the one being inside with the other out. Although I've never tested if blocking a signal causes any kind of delay compared to a lesser or unblocked signal. But what I'm saying is that any difference signal timing of sign waves will tend to cancel each other out. The delay being caused by a difference in resistance, hence the use of attenuators to essentially adjust that resistance.

[@MrBOB39]

Yes... I wrote just that... he Fully missed that and that is a very importent thing to know using multiple antennas of the same frequencys

[@tmcquinn]

After the repack, nothing worked for me until I got a directional antenna. It even works fine in the attic. But I had to choose between the nearby stations to the south and the northern stations 35 miles away. A rotator is not going to work here. Attic mounted is working fine but I have to choose my direction. Is there any chance that I could mount a sheet metal shield in the attic oriented from east to west, put a directional antenna on each side of it, then combine the signals with something like a Channelmaster Jointenna? Or would I still likely be getting multipath from the strong nearby stations to the south?

[@AntennaMan]

Channelmaster Jointenna would still give mutlipath. You can try it but a good chance you'll kill some stations when you combine the two antennas

[@elvislennon6795]

I just got a radio shack tv antenna and it really works great ! Can I hook up a clear tv antenna with it ? Will I be able to pick up more channels with it ?

[@STBRetired1]

Well, this was the only video that described my problem perfectly. But, I was hoping for a miracle gadget to hook up to the two antennas to make it work better. What I have found, though, is by pointing an antenna at the far away stations and disconnecting the cable from the second antenna that I was using to pick up local stations then I can get all the stations. Somehow, the disconnected cable seems to pick up the local stations okay but the signals go all wonky when hooked up to the second antenna. I've noticed that signal reception with two antennas varies from day to day depending on weather conditions and time of year. UPDATE - I found something that helps. I was using to equal model antennas - one for distance and one for local. I switched out the local antenna for a smaller, cheaper unit and that seemed to stop the interference and lost signals. Now I can watch the signals from 40 miles away and also those that are only 5 miles away.

[@bigloudnoise]

Seeing a lot of people saying multipath interference is being caused by the different lengths of coax, which is true, and that using identical lengths of cable will fix it. However, isn't multipath interference also potentially caused by the signal bouncing off terrain/buildings/etc? At least that's what I was taught. I.E. you have two combined antennas on a passive splitter, as in example #2, one pointing north the other pointing south. You're watching a channel that's using the "north" antenna. It picks up the signal...but that signal also travels a few more miles where it encounters skyscrapers in the downtown of a large city. The buildings reflect the signal back, where it is then picked up again by the "south" antenna a few milliseconds later. In these cases it wouldn't matter if the coax cables are the same length or not, you'd get multipath interference and loss of signal anyway.

[@AntennaMan]

This is very true. I say it's best to have reliable reception from one direction than half ass reception from two directions.

[@tom7601]

bigloudnoise: I was an antenna installer starting in 1968. We lived between San Diego and Los Angeles so most locations had channels 2-4-5-6-7-8-9-10-11-13, 15-39 (UHF). Most installations used a rotator, but some used two antennas and a switch. A weak signal required a preamp. In those pre digital days, we had snow and ghosts. Now days we have NO SIGNAL! :-)

@@tom7601 i love hearing from former installers. My grandfather was one from the 1950s until the 80s. That's how I learned a lot of this stuff.

[@voxelmaniam]

Ok, that said, out here in middle of nowhere Iowa the terrain is relatively flat and a tall building is a water tower here and there. I just installed a Xtreme Signal Long Range Yagi Style VHF/UHF HDTV Antenna (HDB91X) with a Channel Master CM-7778 Titan 2 "Medium-Gain" Mast Mounted Preamplifier to pick up the stations that are of primary importance to me and 47 miles away on the same transmitter. They are now coming in load and clear. There is another station, PBS as it happens, that is almost 180° in the other direction also of interest. I am thinking of installing the exact same antenna and either another CM-7778 or the stronger CM-7777 given the additional distance at 58 miles. My only concern is that there is a nearby (12 miles) transmitter 35° west of the signal of interest. I get these signals poorly on the first antenna. Are these likely to cause interference with the weaker signals that I'm now getting clearly? The real center channel frequencies are 33 for the first transmitter, 12 for the PBS transmitter and 15 for the nearby transmitter. I'm not really interested in watching the channels coming from the nearby transmitter.

My preferred method is number four, to use a good directional antenna with a rotator. The only problem is getting the TV to scan and lock onto all the stations without having to rescan each time I turn the antenna.

[@dennisgarber]

The solution is the televes smartkom. I have been fortunate and I have been able to avoid tuners that do not have a channel add feature. How has the lifespan been for your rotors and what climate and shade, snow, sun per day, latitude, number of sunny days per year? I wonder if a plunger could be modified to keep the sun and rain away from the rotor to dramatically save the rotor? . Or some other less obvious trick.?

[@charlessmith1890]

The main stations in our area are in two opposite directions 183 degrees apart so I built an antenna that picked up off either end with a center live element which h worked great.

They were on the roof and on same pole.All he used was a splitter.

[@AntennaMan]

Combining them like that can work for some people but if the signals are weak (like in my market) you will get multipath interference and lose channels.

[@The4Crawler]

Another option to consider is hooking up 2 (or more) network TV tuners, like the SiliconDust HD HomeRun tuners. Connect one tuner to one antenna, another tuner to the 2nd antenna then combine the 2 tunes in your media server. My buddy used to do this with a small whip antenna for the local stations feeding one HD HomeRun and then had a long distance antenna for stations about 90* away with 1 or 2 additional tuners. I'm half way thinking of adding a 2nd antenna to pick up some Lo-VHF stations to the south of my main stations. I already have 2 HD HomeRun tuners, so would just need to separate them onto different antennas: kzbin.info/www/bejne/ZpmUpX2HYpZqj5I
