Sure, especially if you can use a decent radial system or counterpoise with it. Would a taller antenna be several dB better? Of course. But as one presenter at a Dayton QRP conference said so poetic
Mike, definitely worth a go. I had used a quarter wave raised vertical on 40 metres for some years. The feed point was at 11 feet above ground with sixteen quarter wave radials dropping down from 11
Depending on the exact configuration and surrounding antennas and objects you may see some high angle radiation on 80 meters. I use what I call a fan vertical. I have 80 and 160 meter wire elements s
Hi Mike, I have a dual-band 160/80 meter vertical system that is based on 1/4-wave verticals on 80. I switch in loading coils to make them work on 160. The 160 capability was added as an afterthought

Thanks all for the comments. I am putting up a single DXE 80m 1/4 vertical. I can put out the proper radials. I will have to add some longer ones for 160. Now to figure out switching in and out 160 a
Hello Mike, There are a couple of guys in IL that have 80M zero-five verticals with a vacuum relay at the top. The relay switches in a top loading wire to make an inverted L/T antenna for 160M. They
I've got a 160M antenna farm to die for, and have worked hard at it, running legal limit. After 8 years in CA, I've worked 131, all confirmed. Yes, it sure is different on the east coast. 73, Jim K9Y
Not as difficult as you might think. Certainly worth some modeling. Add a 80M trap at the top between the vertical and horizontal portions. Below 80M that circuit would look inductive, which adds loa
Mike, Can you find or provide more info on these 80m zero-five verticals? What does zero-five mean or stand for? I though about using relays to switch in/out the top loading wires for 160m, but compu
I am putting up a single DXE 80m 1/4 vertical. I can put out the proper radials. I will have to add some longer ones for 160. That's a good vertical, and the 80M radials will probaby be adequate if y
I used Deltrol relays from Surplus Sales of Nebraska to switch my matching, $24 and rated at 6kV from memory. Working fine at 400W even on my very short radiator. I am putting up a single DXE 80m 1/4
I have the zero five 55 foot antenna which was custom built to actually be a full sized 80 meter antenna. It was affordable and has stood up well on a very windy mountain top. Performance is, of cour
I though about using relays to switch in/out the top loading wires for 160m, but computed the voltage to be over 10 KV. Vacuum relays to handle that voltage are very expensive. Then there is the issu
My current antenna is somewhat what you ask about Mike, its 70 ft vertical with two top hat wires to resonate at 1830. the top hat wires slope down to perhaps 20 ft high. For 80 meters I switch in a

Mike, No need for traps and horizontal wires and such. Put a 160 resonator on top of that vertical. Use a low Q long skinny coil with a nice big capacity hat of 25 pico farads or so. It won't affect
