That is CORRECT ! Although... HE DOES NOW !! His story came up during a similar conversation on a short wave radio discussion group, and similar to the original inquiry on this thread, his listening
Most studies concur that "buried radials" should not be deep but preferably at the surface. Hear, Hear !!! Surely the goal is the grab the RF before it can be absorbed by the lossy earth. My wife is
All my ground loop problems went away after Bob, K4TAX, and Jim Brown, K9yc, talked about this same thing on another reflector a couple of years ago. It now seems so blamed obvious... like smacking y
Oh... Kriss... I implore you to AT LEAST double the number of radials ! 25 would be a really good number. You can roll out 45 feet of wire, and crimp on a lug, and lay it in the yard with some wire l

My friend is a home builder ... and he advised against drilling holes in the basement floor. Water entering the basement is just one of the reasons he advanced against. Just MY take... -- K8JHR -- __
Cool. Just think what he could do with a REAL antenna !! ;-) But seriously, folks: You advance an odd sort of argument. Apparently, you consider it more admirable to enter a contest and fight tooth a

First, I think that if you modeled a ground mounted vertical and the same vertical at 330 feet above ground, you might find the radiation pattern (take off angle) would not be the same for the two i
That depends on how the end fed half-wave dipole is fed. See my Coax Chokes Power Point for one form of end fed half wave dipole that does NOT use the coax as a counterpoise, but DOES use the coax s
If your local soil varies so much that your radial currents are not balanced, the effect will likewise alter your pattern, but that does not prevent the vertical from working as expected, it just ma
I am a late bloomer in ham radio. I was not an engineer in a former life, and am still grappling with basics. I still find matters of IMPEDANCE ...SWR... reactance... radiation resistance, etc., a pu
Thanks, Stuart. I will look for the treatises you mention, and add them to the several books I have now. I have a pile of ARRL books, a few by a guy named Orr, and one by Joe Carr on receiving antenn
