Affiliate Link CM7778 on Channel Master's Website: bit.ly/33BPj1v If the preamp doesn't improve your reception consider a custom antenna recommendation from me at the link below. I run a reception report at your location and determine what antenna would work best for your area. www.antennamanpa.com/antenna-recommendations.html

[@classic287]

I know someone who doesn't understand "you get what you pay for". I have a long cable going to my antenna. Maybe I'll tryout one of those amps...Great that you explained it in detail. 👍

[@TejasToolMan]

Make sure you have the right coax & that its not been fried inside by voltage spike, 20 feet up the antenna mine was burned into inside the coax

[@6actual911]

Back in February I asked Antenna Man about getting better reception our farm house in Nacogdoches, Texas where we got 3 out of 8 available channels only. Antenna man looked at my all information and told me to shortened the cable runs (which were too long) and Install the Channel Master CM7778. And I did it all. And wow... I was trying to get in 8 channels.. to my surprise we get 14 channels !! All channels come in great and in HD or really clear and strong! Thank you Antenna Man!!

[@JoseYou317]

Just installed mine plus an LTE/5G filter and my OTA signal improved 100%. No lagging, interruption or pixelated signal. Thanks

[@bge7744548384]

Had an Antennas Direct ClearStream 2V TV Antenna in my attic with 35 to 40 stations from Baltimore and Washington D.C. Best response was 35 to 40 channels with some 3 and 2 bars with good reception but at night or in windy weather it was not always good. Installed this Channel Master CM7778 Antenna Preamp and now we get 70 channels and all major three networks with 5 and 3 bars. We are in the Annapolis area and had our antenna aimed at Baltimore but had better luck aiming it at Washington D.C. because the stronger Baltimore channels still came in OK with the amplifier even though Baltimore was 90 degrees from the antenna fucus at Washington D.C. Works great! Thanks for all your good advice. Keep up the good work.

The dish was there when I moved in. I might make a video on how to connect an antenna to an existing dish pole.

[@Gratefulwon]

I used one of these for nearly two decades before it failed. I live in a decent signal area, the installation has a long burred cable of about 80 ft total length. When it failed, the internal pc board looked like it was baked under a couple components. I replaced it with a cheap walmart one and good for nearly two years. It was all I could find on short notice. So far so good.

[@RarestAce]

I have the Channel Master Amplify dual gain preamp and that unit has been working perfectly for us Since i did my OTA setup in 2017. Great Video as usual Brother.

[@druliefw]

I have been using this pre-amp for about 9 months now. I also attached a high-pass filter to filter out my amateur operations and a new model LTE filter that filters out 5G signals. It make a big difference in receiving WLVT (RF9) and WFPA (RF35) to get Quest TV which is a low power station here. This amp is also doesn't get overloaded by the strong stations I get from Philly. I'm only 18 miles from the towers. The antenna is the Wineguard HD8200u on a rotor.

[@AntennaMan]

It's a good preamp.

[@jimownby3234]

I have a small directional outdoor antenna running to a splitter which routes signal to two televisions. I am receiving from approximately 32 miles from a cluster of transmitting towers. My cable run is about 36 feet. The one VHF channel I receive was over 27 db SNR without the amp. The UHF channels were anywhere from 13 db SNR to 23 db SNR without the amp. The ones below 14.5 db SNR would either randomly lock or only lock at night when the sun was set. I installed the Channel Master CM-7778V3 Titan 2 medium gain amplifier at the mast. With the amp running, the weakest UHF channel now stays locked with 19 to 21 db SNR. All other UHF channels are locking with 21 to 28 db SNR. The one VHF channel is over 31 db SNR. Overall the average increase is about 6 db and these figures are post the splitter. I am not running a distribution amplifier. I am amazed at the difference this amp has made. Every single channel is now reliably received, this is reviewed after dark on a clear night. I have not tested in high sun during the day or during a rain storm yet. I would buy again. I wish I had bought years ago. I highly recommend. I give give five out of five stars.

[@nhojcam]

Tyler, I recently found you here on YT. Thank you for your channel! We just cut our cable and are saving $98/month. I ended up doing an attic install with a Clearstream 4 Max antenna and will be adding a CM-7779HD (yes, I used your link on Amazon!) pre-amp this weekend. All of our local TV channels are broadcasting on UHF. I have a cheapo Clearstream inline signal booster ($20 from Walmart) which isn't getting the job done, plus I suspect 4G/LTE/5G interference from lack of crispness on the higher RF channels. Without the cheapo signal booster, but with dead-on alignment using the tools you recommend in your other videos, my channel count goes way down on the 45 mi towers. Plus, I have a long run to my TV (50+ feet of RG6). So, the CM-7779HD should meet all of my needs. Thanks again for your good content!

[@nhojcam]

UPDATE 12/8/23 - I installed the CM-7779HD today and re-scanned for channels. Before the preamp installation, I was only intermittently able to get some channels...even with perfect alignment. Unreliable at best. My closest channels, considered to be our local stations, I was able to get a solid 34 channels with great pictures (40mi locals) with the Clearstream 4Max located in my attic. There were out-of-market channels (20 or so) that showed signal strengths of

[@codyway7424]

We had the high gain model just like yours. At about 10 months, it stopped working and blocked all signal from reaching the TV. Once removed from the antenna, we still get all the channels, except for 2 very distant ones. The pre-amp is currently on its way back to channel master. They have a 1 year warranty.

[@sergioleone4215]

I just posted a comment above. My parents had their new Winegard antenna connected to a ChannelMaster preamp and it basically blocked the signals. We bypassed it and now get all of the channels available in our area. We think it was dead from the day we purchased it.

[@charlessmith1890]

This is Chuck Smith the original Antenna Man. I have put a few hundred channel master preamps over the years and am still using a channel master 0264B preamp that I put on my antenna system in 1978. I did have one bad one one time in 1979 on my tower at 80 feet at my business. When the tempura outside would go above 72 degrees it would quit working, when it dropped below 72 degrees like at night it was good. Since it was new I took it back to my distributor and replaced it. Other than that I never had any problems with Channel Master.

[@brucegl4298]

@@sergioleone4215 You mentioned in a previous comment that your parents' home is about 34km away from the Chicago transmission towers. Tyler has noted that the preamp was delivering TOO STRONG a signal to their TV. If they were 100km away, it may very well have worked fine.

[@ThatEEguy2818]

You forgot to mention noise figure. Even if the coax is short, a low noise preamp can help "fix" a high noise tuner. Some TV's are more sensitive than others and have higher noise. The first amplifier stage usually sets the signal to noise ratio for the system so if the preamp is low noise, you may receive signals you wouldn't get even with a short coax.

[@Bruce_Wayne35]

"The first amplifier stage usually sets the signal to noise ratio for the system..." Exactly. A lot of people don't realize this. Apparently, when you add a preamp in-line, the tv's rf agc circuit will decrease the gain of that first rf amplifier stage in the tuner. When that happens, the noise it contributes will decrease as well. The typical noise figure for that first rf amplifer stage inside your tv's tuner is around 8 db NF (for a UHF channel), which is pretty high. So a preamp with a 3 db noise figure will improve the overall system's noise figure by 5 db, which is huge and can make a big difference on a weak signal, even if the preamp is sitting on top of the tv.

[@ThatEEguy2818]

@@Bruce_Wayne35 It's amazing the difference in tuners out there. I live north of Detroit and in the 80's, our Zenith would pick up more channels than our RCA. Channels from Toledo that the RCA could barely get came in halfway decent on the Zenith. The Zenith was portable and I did move it to the RCA's location just to verify it wasn't an antenna cable issue. It wasn't.

[@4pharaoh]

Yup, Noise Figure on weak signals is the most important consideration. 4 or 5 DB is too high. Below 1 DB exists but $$$

I want to say thank you. I saw the list of recommended antennas and accessories that you listed. And I tried the Mediasonic ATSC Digital Converter Box.

[@sergioleone4215]

My parents lost their OTA TV signal about a year ago and went from about 65 channels down to around 11 in the Chicago market. They are 21 miles from the transmitters. They bought a new Winegard rooftop antenna and a ChannelMaster Model #CM-7777HD preamp. We installed the new antenna and preamp and did a channel scan and it stayed at 11 channels, which were all weak and pixelated. I decided to swap out the RG59 cable in their attic with a new quad shield RG6, and replaced their 4 way splitter with a new one at the same time. It was a brutal job climbing in their attic when the outdoor temps were in the 70s. Must have been 110 degrees up there and I had to crawl around since there was no headroom. The new cable and splitter made no difference after a rescan. I was about to give up but thought I'd try one more thing. Went back up on the roof and disconnected the new RG6 cable from the preamp output and connected it directly to the antenna balun using a female to female connector. Ran another channel scan and boom, we now have 73 strong channels again. The Channel Master preamp must have been defective or something. It was a waste of about $90 and caused much gnashing of teeth. I'm pretty sure that the original loss of signal issue had something to do with a nearby lightning strike or something similar, because once we replaced the coaxial cable we were able to get a signal again. Glad that problem is solved.

[@villumschroeder1255]

Interesting. Bummer you had to waste all that time and effort. Your experience proves the antenna reception chain is no stronger than its weakest link.

[@RarestAce]

Odds are the preamp was not needed and you were overloading the receivers with to strong of a signal. The preamp wasn't defective your setup just doesn't require one. Or you had the power inserter connected wrong.

[@landochicago]

Tyler, you are the best! I have learned so much from watching your videos. I had this preamp lying around because I tried to use it with a rooftop antenna in a previous house where it turns out I didn't need it. I have since moved farther out and now have a cheapo GE 33692 mounted outside (I know, I saw your review after I bought it). Amazingly, that picks up the 2 weakest signals in this area (WBBM Channel 2 at VHF 12, and WMAQ Channel 5 at UHF 29), but fails with the strongest signals. So I figured I would try this amp out with the GE. In theory the other strong signals, all UHF, should be coming from the same coordinates as the 2 I get well, namely top of the Willis (formerly Sears)Tower. Also, I wondered about your opinion of tvfool vs. AntennaPoint vs. ChannelMaster. Only the CM website showed how actually weak all channels are in my location based on my address; I wonder if it's taking the lake I live near and the many mature trees nearby into account. Also, all of these sites show slightly different azimuths for the transmitters, but the CM site seems most accurate.

You need to purchase a separate LTE Filter from Channel Master to reflect the recent 2020 FCC repack as this filters out frequencies greater than 610 MHz. This product does not cutoff frequencies greater than 610 MHz as of October 21, 2020. This pushes the purchase price for this preamp + LTE filter. FCC repack was completed in July of this year.

[@dougb3699]

It might be good to note that cable loss equals noise. That's why placing the amplifier at the TV will not work. When placing the amp at the antenna, the cable becomes 2nd stage contribution and is negated by the amplifier gain. Sorry about the technical stuff but my brain just goes that way.

[@Pallidus_Rider]

Signal should be tested at the antenna and also at the end of the cable run to determine if there is loss. If yes, a preamp would likely help. 🤓

Update on the Titan 2 channel Master preamp install - I had 36 channels - some weak channels . Installed this Channel Master Titan 2 and when I did a channel scan it reduced it to just 7 channels total . What a piece of crap .....Going to take it off and send it back ....had high hopes of bettering the signal strength . I'll just go back with no preamp and be happier than with one . I had probably 3/4 the channels that I could watch them it when it went to 7 total . Like the channel ... your a smart guy Tyler . Alls well , the Titan 2 isn't for everybody - read great reviews on it tho .

[@AntennaMan]

Don't blame the preamp. You are just barely getting the signals so adding a preamp increased the noise floor to the point they no longer come in. The same would happen with any other preamp.

[@marshallborder9089]

Antenna Man Sending it back never the less for refund , I'll live with my 19 channels for some of the time , and the other15 all the time without throwing money away for a preamp that doesn't work for my needs .

Anyway I'll just live with the results .

[@AntennaMan]

@@marshallborder9089 Some people are in the same boat where a preamp just wipes out most of their channels. Let me try to explain it. There's a noise floor and a TV signal has to be above it in order to be decoded. Let's say you're just barely getting the signals at 1dB above the noise floor. When you add the preamp there's 1.5dB of noise added which makes the channels now .5dB below the noise floor. One thing I'd suggest is to make sure you have a good, large antenna (not a small one if you already have one) and use a high quality RG6 quad shield cable.

[@jeffhartman7000]

The 7777 is a very good preamp for fringe areas where the signal is weak. If you are closer to the transmitters, it’s entirely possible to overload this preamp, which will make your reception radically worse. The ideal case is to use just enough preamp gain to bring the signals up out of the noise floor and to overcome cable and splitter losses.

I live in Northampton Pa and with a small crappie RCA antenna from Ollie’s I pick up all but ch 3 and 10

[@AntennaMan]

@@stevel6885 That's where I live. You likely need a better antenna to get 3 and 10. Consider a custom antenna recommendation from me at the link below: antennamanpa.com/antenna-recommendations.html

What signal meter do you use?

[@sherrilmason1195]

I have a request can you review the antenna from my Cable Mart it has three mast booms and four reflectors

[@TwinntechFreeTV]

is this reflecting the repack uhf range or is it still supporting ch69+

[@AntennaMan]

I'm not sure what you are talking about. TV stations broadcast on RF channel 2-36 but that doesn't matter as the preamp is amplifying all frequencies.

[@davidsteen2777]

You had mentioned you use a signal level meter...what do you use? Thanks for your input!

I use the signal meter on this DTV box below. If you press the info button twice it will bring up a signal meter. amzn.to/3a1lrvR

What's your opinion of Dennys Stacker antenna?

[@AntennaMan]

It looks like a decent antenna but I have no plans to review it as it's no longer sold online.

[@km-bo3zx]

There are preamps that have inputs for multiple antennas, what would be the correct way to use this with two antennas?

[@AntennaMan]

I have two videos on this topic - combining antennas and the CM7778HD review.

[@truthbespoken7750]

#AntennaMan thanks for the years of great videos and information. I currently own the Antennas Direct CV2 and was contemplating if I should get the Channel Master 7778 to see just how if any, I would receive a better signal reception. My issue is my area, 2 streets over is Amtrak and some antenna signal repeaters. Would this 7778 help or make things worse ? Thank you. Dave@401

[@404010ful]

Tyler I have the old 77778 HD when I get a channel master antenna can I use my old one if it still works? Or get the one your reviewing?

[@AntennaMan]

Yes you can use your old preamp!

[@shnobi24]

If the pre amp were to fail or in a power outage, could you still watch OTA television but with only the strong signals coming in?.

[@AntennaMan]

No this preamp doesn't have powerless pass thru. If your area is prone to power outages don't use a preamp

[@pgchase4578043026]

Is there a way to amplify just one RF frequency? RF 15-1, 2, 3 is a lower-powered station, while the other 56 channels all come in fine. I read on the Channel Master site that sometimes an amplifier can make things worse if you're amplifying stations that don't need it.

[@Bruce_Wayne35]

I think there are single-channel bandpass filters available which can do that. You could put it on the input of a very high gain, low-noise preamp and this setup, along with a single-channel yagi, could be used to receive a weak signal. The filter should keep strong local signals from overloading the high-gain preamp. www.sateng.com/downloads/3278.pdf

[@WiSeNhEiMeR-1369]

HOWdy A-M, THANKS COOP ...

[@Hell_Toupée]

i am a llittle cofused. who has an electrical outlet close enough to the roof to be able to mount this on the actual antenna pole? I have zero outlets outside the house on the side where the antenna is....the cost of installling an outlet just for an amplifier makes 'cutting the cord' even more expensive

[@AntennaMan]

This preamplifier does NOT get power through an outlet near the antenna. It gets power through the coax cable that runs inside the home with an included power inserter.

This product has not yet been updated to reflect the recent FCC repack.

[@AntennaMan]

It doesn't have to - it still amplifies the same RF frequencies the are broadcasting and works fine as you see in this video.

[@williamquemuel7824]

Channel Master website shows that the frequency range still covers up to channel 51. You stated before that the FCC repack cuts off the UHF band up at channel 36. The FCC repack completed in July of this year. I know that the product will still work, but bands that once resided between channels 37 -51 are now free for wireless devices.

And the one channel I wanted but never came in before the CM7778 now comes in briefly pixilated, so it is still unwatchable. Gonna take your video advice and go get a better antenna.

[@falsedragon33]

I don't understand. Your aren't reviewing them. Your selling it. I have yet to see you test any of your anteenas for swr, gain, or any real kpi. The same for this LNA. What is the dynamic range, or why not measure the gain, and show how nasty these things amplify, and why a cellular engineer knocks on your door, telling you to shut it off.

[@AntennaMan]

I don't sell any products. This review is to help people and an informed purchase. I don't need crazy technical testing of this preamp. You can clearly see it increased the signal and brought back three channels. That's all 99.9% of people care about.
