Why not Bob? I have a tough time sorting out the experts from the non-experts, pseudo-experts, and "real" experts. I, for one, would enjoy your help in determining what comments should be deleted wi

To: <towertalk@contesting.com> -- This should work absolutely fine. The only precaution is to use battery supplies only, and move your mitts off the case to take the actual reading. The Autek, if lef

To: <towertalk@contesting.com> Hi Eric, That can not possibly be the problem. The Autek is a small instrument, and as such has a case and circuitry that occupies a very small fraction of a wavelength

On airplanes. It takes a big wick to discharge the earth to a cloud. A non-conductive path to the charged cloud renders them useless, because they can't discharge the cloud to earth. You'd be VERY h

To: <towertalk@contesting.com> Hi Dick, Radials help any ground mounted or near-ground vertical, the more the better. Radials do two jobs: 1.) They give some antenna designs something to "push" again
