I have one mounted at the peak of my roof (about 30 feet above ground) in a suburban residential area of Columbus, Ohio. I also have a horizontal dipole at about 25 feet. I operate barefoot at 100 watts maximum output. I meet two friends from childhood on 20-meter SSB each week at 1600Z, one in Fresno, CA and the other in east Texas. The one in CA runs barefoot with a horizontal dipole at about 30 feet. The one in Texas is a "big gun" with KW amplifier and a tribander at 75 feet, with an R7 on the same tower, above the beam. He works both of us with the side- lobes of his beam and always has S-9+ signals at both ends. My friend in CA and I do well during good propagation if we have a clear frequency, but often poor propagation and/or QRM make it very difficult. But my signal in CA and his signal here are almost always about the same, with PERHAPS a tiny advantage for my signal over his. When I try my horizontal dipole, my signal drops a bit, perhaps one S-meter division. The Texan doesn't use his R-7 with his amplifier and when he tries to work us with the R-7 barefoot his signal is down considerably, so he doesn't do it often. I can't give you a numerical measure of how far down that is. Sometimes we shift to 17 or 15 meters and, if the band is open, the contact between CA and here is superb, S-9+ on both ends, but I lose Texas because of the skip. I worked some DX during 1991-92, CW only, and found on all bands from 14.0 MHz. up, that I can work anything I can hear with the R-5. I hope this is some help. 73, Van - W8UOF * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * It ain't wot you don't know 't gets you into trouble. * * It's wot you know 't ain't true. - "Mr. Dooley" * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * wvanhorn@magnus.acs.ohio-state.edu ------------------------------ Date: 27 Jan 94 08:32:38 -0600 From: nic.hookup.net!paladin.american.edu!howland.reston.ans.net!mrtnt.ntrs.com!tntvax!ddb@tcgould.tn.cornell.edu Subject: Help - Vertical opinions needed To: ham-ant@ucsd.edu I'm looking to buy this weekend a ground independent vertical for HF.

I suppose I could get it through NTIS on 9-track tape for a hundred or so bucks, but I'm hoping someone knows of an ftp site for it. While we're at it, how about the source for minimuf?

There may be nearby transmitter(s) that will cause the scanner's front-end to overload, therefore dsensitizing it. The problem doesn't take place with the rubber duck due to the decrease in signal strength.
