My son KC2PWX is looking for a solution to a 80 meter antenna, problem is he has about 30-35 vertical feet he can go. He is using a ground mounted 5btv but is is awful on 80. Any idea? John J. Nistic
I would recommend an inverted-L. 30-35 ft vertical is fine and run the rest of the wire as horizontal as possible. Use 3 or 4 tuned radials above ground or full radial field on the ground if preferre
I have dealt with this problem a couple of times on DXpeditions. Here is what worked for me and I use some of this solution today at my home station. I have found that central loading of elements tha
I built a full sized guyed vertical and carried it in my luggage to ZF2 and VP2M. It was a little scary putting up, with the XYL but it worked pretty well. Another option for loading a short vertical
I've used a Butternut HF-2V, 40 - 80 vertical which is NOT trapped but uses capacitance to work around the adjustable 80 meter inductance. In my installation I've used "umbrella" top loading with fou
Hi John, Back in the 70's, on a city lot in W9 land, I used a 40M vertical and added a make shift ~12' diameter top hat. Maybe more like an umbrella hat but it did it's thing. All you needed at the b

I did plenty good with an HF2V (26 feet). I did very poorly with it on 80 until I put in adequate radials. It performed well enough (though not as good as it could have) with lousy radials. There's a
How many radials and how long are they? The 5BTV is a loaded quarter wave vertical, so it requires radials -- without radials, it's a worm-warmer. On the ground, it needs a LOT of radials. Can he rai
Try Lasy-U or Lazy-H vertical dipoles. it's a vertical dipole which is end loaded. built one as tall as you can go and then extend top and bottom until it resonates at 3525 or whatever you need. I us

I second (or third) the HF2V. I had one up with about 60 radials for about 6 years. Before I put it up, I had less than 30 countries on 40 and 80. When I took it down I had 240 countries on 40 an
Is the 35' a tree? If so, go for an inverted L (or T) with a couple raised radials or *many* on-ground radials. If he can't use the 35' tall 'support' for an inverted L (or T), then my 2nd choice wou

... and no mention of the K2AV FCP with Inv l? Space saving and no radials. I have one on 80 and one for 160 - very very Happy with their performance. 73 Dwight NS9I John J. Nistico 911 Electric Inc.
This would probably be a good place for an FCP radial system. Takes up a lot less room. http://www.w8ji.com/fcp_folded_counterpoise_system.htm Tom W7WHY ______________________________________________
What is his objective, DX, or local? The answer will dictate the antenna choices. 73, Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true
Is he limited to a vertical? If not (and I hope not) a long dipole as high as he can get it should work quite well. I have had a lot of success with open-wire fed antennas of many configurations at t
That's an urban myth. Yes, verticals have little or no high angle radiation, but that only matters if you're trying to ragchew within a few hundred miles. See the links I posted for some real science

I agree with Jim, I had a pair of ground mounted, 1/4 wave verticals on 40 with a mediocre radial system and a switchable figure 8 pattern broadside or end fire. Their main advantage was reducing the
John, Most of the comments have assumed that your son has adequate space for a vertical. I have seen many terrible, limited space vertical installations, where the antenna is no more than a few feet
