Something to consider structurally, the solder removes any flexibility in the stranded copper wire. So make your solder connection away from a pivot point. That way it won't cause your wire to break over time with movement (wind etc.). 73's NG7I

Great video! One thing I would advise those doing this project; when making any wire antenna, I temporarily mount it on a pole in the yard before stringing it up high, this way you can trim or lengthen without climbing back up the tower.

Awesome video! All I have to say is there are a ton of instructional HAM videos here on KZbin, but yours is one of the most professionally done. I find this video to be very informative. You speak clear and concise, and your camera angles are spot on. I can only dream about undertaking such a project. Unfortunately I don't currently have the resources at my disposal, and I live on the ground floor of a 3 story apartment building.

Tip: I've been playing around with building antennas from scratch the last couple years and since we're already using "metric" for the wavelengths anyway, I decided to just DITCH the imperial tape measure for a metric one so I don't have to "convert" any measurements or deal with fractions or mess with converting 10ths of an inch to a fraction either. HOLY COW was that the BEST $8 I think I've ever spent on ham radio! Not only do you save the time it takes to convert measurements but it's also a HECK of a lot more precise, there's more increments "per inch" if you just use metric. Good video BTW, I keep debating whether or not to build one of these, but I'd need to make a "vertical" one for my quad band radio with 70cm/2m/6m/10m.

The fan dipole uses way more wire than a good OCDF- Off Center Fed Dipole. The standard configuration to start with is 90x45, and use a balun Design OCFD balun for the best results. That balun is marked as to which side the longe element goes to, so make sure you get the correct balun. I can work 2M .70CM, 6M, 10M, 12M, 17M, 18M, 20M, 40M, and a smart part of 80M on my OCFD using no tuner. If I use the Tuner, it helps on some bands that have a narrow window of use. In all cases, the antenna works really well. The fan dipole has a few things it can do due to the proximity of the elements to each other. The only bad thing that can happen is to generate harmonics.

Great visual! My house in Oklahoma sits on a diagonal and the hypotenuse of the roof is just over 63 feet with a roof vent right in the middle that I should be able to tie the center feed off to. With some stand offs on opposing corners of the house, I should be able to get that 65.9 feet out of it perfectly without having to stretch to any trees, which is nice since I have no trees. That will broadside me almost due east and west! Thanks for the video!

I made one for 160m-75m (half wave) and it works great. I just added a Balun Designs 1:1 to the center and will be adding 60m. I did not bother with insulators and just strung the legs out at different angles from the tower. I also keep a "balun pully" on my Rohn 25's hazer for easy up and down of the dipole from the ground. You will always need a tuner for broadband operation of these dipoles. 73

Sounds great, it should work very well for you, as good as a full size dipole on each band you cut it for and if you might not even need the tuner but if it is off a little the tuner will help to tweak it right in without needing to prune each wire as long as you are close. And you should be able to use on any band with tuner and it should work fine except on 160, still possible on 160 by just shorting center pin right at tuner and using separate ground wire for 160.

leo sav I made my own mag loop, in about that same size - I used the air variable tuner capacitor from an old Hallicrafters S-38 receiver, and it works well for listening - it could be used also for QRP transmitting, but I have not tried that yet. Basically a loop of LMR600 cable for the main loop, with a small loop of LMR400. It will tune 80 meters and all the way up past 20 meters. Just tune for maximum noise on the band you want to work. I am in an apartment and listen to 3913 KHz every night...

Yes, it should work a little better than a G5RV antenna since it is a full quarter wave on each band, sure been working well here, no complaints. Although, for just a mono band dipole, the coaxial dipole might be a good choice, they are very broad banded.

Yes it is about being as high up as you can go with it, but it will still make plenty of contacts at a low height. It will just not be as good for longer distances and DX if closer to the ground. It will actually work better for stations within a few hundred miles when lower to the ground since it radiates higher into the air instead of a low angle take off so signal is reflected down from the sky closer in. Stations farther away may still hear you, just not as strong as having it up higher.

How much do things like houses in the way affect the height off the ground? In other words, if I mount this at the apex of my long roof will it be similar to mounting it two stories off the ground, or more like the inches off the roof? I am going to order the ARRL antenna book. New ham here... Maybe someday I get a tower, but the spousal unit would not approve until we move houses. Thanks. 73
@RadioHamGuy
@RadioHamGuy 8 жыл бұрын
It will be like the height above ground but the house will effect it a little bit. If you have a metal roof, that is different, then it will effect it a lot. But with a normal roof, just get it as much above the roof as you can. Just get something up in the air and make contacts and you can always make changes later on as need be. The antenna book is a great investment. Congrats on being a new ham also!! Good luck and have fun with radio. 73

I also have an OCF dipole and I switch back and forth for the one that gives me the best signal in the direction I am talking.

Give that a try, it should work ok, the swr might be a little tricky but if you have tuner, should be no problem. Won't be quite as good as up in the clear but at least it should get you on the air and making contacts. Might pick up a little more noise also and you might want to run lower power if you have RF problems. Another option might be a wire loop antenna as long as possible with an auto couple type tuner right in the attic connected directly to antenna.

I think I tied a knot at the very end of each leg of the dipoles at the last spacer but on the spacers that are not at the end I just used the hot glue, it held very secure and if it did come lose, I don't think the spacers will move around much anyhow. No problems with mine yet and it works just fine, I would think it would work better than a G5RV on the bands you cut if for since it is a full size dipole on those bands but I have not compared it to a G5RV I guess so can't say for sure.

Thanks, well the cost really depends on what you might have on hand but the most cost would be the coax cable depending on how much you needed to get to the shack and the wire for the antenna, but you don't really need anything special for wire, just something that will hold up over time. The PVC I used was very inexpensive, just a few dollars for all.

Larry, I just finished putting up my clone of your fan dipole (as an inverted V). I have the 40 meter band tuned sweet as can be. 1.2 at 7.2 mhz. At 7.1 it's 1.1, at 7.3 it's 1.3. I could probably trim an inch or 2 off....but I'm happy. I'll tune the 20 and 10 meter bands tomorrow when it's light out ( about 5 pm local here in Portland, Oregon...so it's getting dark). :-) Thanks for the video. 73 Phil K7JBL Edit: Spent the day tuning the antenna a bit more. Pretty satisfied so far, but the 10 meter band is giving me a fit. Not sure why but I'm not seeing much of anything happen (on the analyzer) @ 29 mhz.

I guess I don't know what are available for sure these days on autocouplers but they are probably more expensive than just a shack tuner since they are remoted, MFJ might be lower cost if they have one, then you could just make your own loop around the perimeter of the attic possibly using standard wire, another idea might be a magnetic loop antenna with remote tuning. They work well in small space. Just some added ideas, but I would try what you have first, much lower cost and may work fine.

I do like your drawing of radial lengths but I find it more important to be able to read your writing. Good job.

Sounds like the noise is probably coming from some very local things in the house, you might see if you can pinpoint it to something to try to cut the noise down maybe, could be coming from computers or light dimmers or that kind of thing. Or maybe just a lot of things too, then it would be hard to get rid of. I use a pocket AM transistor radio and walk around the area to find the noise sources, tuned to no station.

Thanks. Hey, that is a very good idea, that sure would work and would be cheap and easy I would say. Never gave that a thought at the time but thanks for posting that here, might help some others out! 73..Larry

New sub here. I am originally from northern Minnesota. I see you mentioned being from MN. Just passed my Tech & General rest this weekend. Now I have a license to learn. Haha. I am planning on building a fan dipole myself.

@@RadioHamGuy hey there. I am just now getting putting my HF in the shack. I am going to do a fan dipole on inverted v and branch out to a vertical and loop maybe. What bands are best to setup for? Are you still using this? Oh we usually drive right through Albert Lea on our trips to northern Minnesota. This year we are staying put in Texas. I will miss my Minnesota family. Who knows when this pandemic is in our past maybe we could have a cup of coffee along I-35 one day. 73!

@@brentjohnson6654 Hi Brent, that is nice to hear you have family in MN and go by my town here on the way. Yes, hopefully next year will be a better year and we can get done with this stuff. I don't have this antenna up anymore, I am always switching things around but it did work very well, now I have another off center fed antenna up in place of that. Right now your best bet would be antennas for 20 and 40 meters but soon you will probably want something up for 10 and 15 as well as the sunspots get underway. 73 and good luck, sounds like you are getting set up well. Have fun with radio....Larry

@@RadioHamGuy thanks I am now looking at 3 bands 20,40, and maybe 17. I am also looking to put up a vertical like the DX commander to get better reach and more bands maybe. Yes hope to be done with the worst of this virus. Back to antennas, I get that you change things around. That is the appeal of this science hobby to me.
