In response to Eddy's (VE3CUI) question about anyone using "shortened radials", I have been using these for two years now, with very good results. Coming to TopBand after decades on VHF, I was confus
Very interesting indeed Brian and this is the first real practical approach to proving the point that I have seen in print. But still I think this is only making the aerial 'work' and if the ground c
Brian, All those impedance measurements are very nice, but the fact remains the resistance presented at the base by the radials has little to do with the loss of the system. Radials can present a co

That might mean a lot at only 4 ohms radiation resistance 73 Peter copper (& labor!) resulted in only 2 ohms improvement from 16 to 32 radials. _________________ Topband Reflector Archives - http://w
Hi Guys, The "issue" of ground radials, velocity factor of radials placed atop the ground, buried below the ground, etc. etc. is surely one that will NEVER come to anything even remotely resembling a
RE: Brian Mattson's post of Friday, 19 Dec 2014 12:23:52 -0500 The velocity of propagation in the MF and HF bands along radial conductors that lie on, or are buried several inches in the earth is inc
Actually, I don't believe the Brown et al experiments showed this conclusion at all. Their extensive experiments showed an optimal radial length of about 3/8 wavelength (actually 0.41). This, with ON
Recalling Jim Brown's posting yesterday of Rudy Severn's excellent recent work, the current maximum in a radial occurs at 0.25 wavelength from it's open end & loss will be minimized when that current
