the more i read, it seems raised radials are a fairly easy way to raise the effeciancy of a short vertical. i have a hy-gain 18ht with base loading. can i use these raised radials with this antenna,

A ground screen mesh extending out at least 25' from the base would reduces losses considerably since just 10-20 radials has little effect. At a prior QTH, going from 100 radials of 60-130' to spokes

That is quite an improvement. I had to have dropped the base impedance from 400 ohms to 40 ohms for it to do that. Dave WX7G _______________________________________________ Topband reflector - topban

Hi, Tom Well, I also used a 40m GP with 4 elevated resonant radials about 6' above ground and I worked an awful lot of really good DX with it!! I found it to be about equal to my half-wave vertical d

Charlie, I will post my results. I had a vertical dipole up before and now am using the 40M GP. The vertical dipole "seems" to be the best performer for DX but what does that mean, hihi. I thought I

I am very interested in the comparison. I am almost daily on 40m SSB at about 15:00 for LP with a couple of friends. The San Diego area is also good for SP a bit later. RBNs in Europe most of the tim

One thing I've wondered: are elevated radials more likely to pickup local QRN than those on the ground, or buried? The on-ground 160M loop antennas I've used for reception seemed quieter here than th

You ever wonder why a few on here are so much louder than their competition with similar installations when 1-2 keep trying to make us believe it has nothing to do with the radials beyond a small num

Or the person on here who went from an extensive radial system to a full screen claimed a 5dB improvement but now denys the possibility. Its in the TB archives from 1998. Carl, Please try to stop tha
