I mentioned before that I thought we should consider a radial system for a quarter wave vertical to be just a counterpoise, and it turns out that a bit of research says that is obvious. That wouldn'
Thanks for the comments, Jim. Well, the reason I don't think a radial system necessarily provides any shielding effect is that there is VERY little difference in either takeoff angle or maximum field
It does not need a radial system of wires to avoid loss. It just needs an alternative path to the earth for near field return currents, and that can be had with a proper counterpoise. The modeling
Thanks, Mike! Yeah, the work you have done over the years with your 4-squares has been amazing. I have been paying attention. ;) As you say, nothing we do can change the effect that the ground has
Jim, I can see where my wording could be interpreted incorrectly since the word "to" has multiple meanings, but that isn't what I said. Read it instead as "alternative to the earth path". That's le
As a system it's the same electrically, but physically and individually I think it's a bit different. A bent leg of a dipole has not very much distributed capacitance and a considerable distributed
K9YC said "Takeoff angle is a stupid concept.". That is hardly true. Focusing ONLY on the gain at maximum takeoff angle may be misleading, but when comparing the same antenna at different heights or
