Agree with N6RK. My T has 8x 125 elevated radials (b4 N6LF work) but is in trees, with the significant losses and is hard to maintain, climbers are unobtanium currently. I am working on a self suppor
On4un writes that many stations find elevated radials to be a few db below ground radials. I believe this is ground dependent. At my new QTH, initially I set up inv U about 80 ft high with 4 125 ft e
N6BT, who has done a LOT of work on the topic of elevated radials, told me that 20 ft is a minimum height for 160M. When I raised mine from about 6 ft to that height, TX signal improved significantly

I've already posted a copy of what N7CL posted to this group years ago. His work, as well as the work of others, can also be found in ON4UN's "Low Band DXing" starting on page 9-14 of the 5th editi
Additionally see: "A Closer Look at Vertical Antennas With Elevated Ground Systems" by Rudy Severns N6LF. He recommends 10-12 elevated radials as a minimum. Wes N7WS My ON4UN is not readily to hand

But what is the *reason* for it working better. Is it something as simple as "the currents in the radials aren't loaded as heavily by something 20 feet away as opposed to 6 feet away" in which case
Here are the facts. N6BT made measurements on 40m. He found that radials inches of the air are much better than many more on the ground. His QTH is OR with very good soil. He also found for ground ra
Elevated radials are finding their way into broadcast sites. Copper clad steel can be used, they are less prone to damage from copper thieves, and in some locations, make it easier to continue operat
I think you may be confusing N6BT with N6LF. Both are serious engineers who combine design and modeling with experimental work. N6BT is a contester and antenna mfr, and has done lots of work with res

Back 20-ish years ago I used to operate from W4WA. Ron had a full-size 1/4 wave made of Rohn 25, with a homemade insulator at 20'. He had 20-22 resonant radials (I don't recall the exact number) even
I wouldn't describe K2AV's signal in NorCal as "great" compared to other I can't either. But I have noticed K2AV's signal is one of the louder signals here in Georgia while listening on my inverted-L
I will have to give K2AV credit in that his signal is always solid copy and pretty impressive for just using an FCP. He holds his own with the other east coast signals here. I can count on a QSO with
I noticed pretty much the same here in Southern California, Rick. I curious about this yesterday, so I looked at RBN data comparing K2AV, N4AF, and N1LN in the 2021 ARRL 160 contest from several node
I am considering the installation of an FCP with an inverted L for 160. It is discouraging to read W8JI's info on the FCP. Sounds like it has too littlle low angle radiation for DX. As discussed howe

Guys, try an inverted L with one radial under the horizontal leg, both 1/4 wave long. From MN I get into Europe on a good day with 100W CW vertical section about 45-50. I drive a rod down only a few
