I am constructing the K2AV FCP Counterpoise for my TB inverted L antenna. I live on a small lakeside lot. Should I disconnect the few ground radials when I install the FCP or leave them connected? Wo

Hi Jim, A lot of this is illustrated for you at k2av.com. Particularly for more complicated situations. I suggest you read the opening page and "Taming the Exasperating Inverted L" at the web site. Y

Explain why more radials over the counter poise. I'm hearing that 1/4 wave radials are actually too long and shorter raises the feedpoint. Mike va3mw _________________ Topband Reflector Archives - ht

I posted what I would, and am doing.  I subscribe to the idea that the radials should be about the length of the vertical as a minimum and using my friend, N7CL's rule of thumb, their number should b

W0MU On, or in, the ground radials are much longer electrically than they are physically because the Vp is much reduced.  How much so, who knows?  Put in enough and resonance doesn't really matter. S

And, apparently, that is like an old wound that will not heal. Radials need to be much shorter and I am trying to find the supporting math. At a 1/4 wave, there is too much ground loss. Mike ________

1): The length to avoid is nothing more than a half wavelength, which translates the same impedance from end to end. i.e., the high Z open end translates to a high Z antenna base end. This results in

I'm not so sure I buy that and I don't think N6LF does either. If you look at the section "An Explanation for the Dips in Ga" (Part 1, QEX pg 40) in Rudy's document http://rudys.typepad.com/files/qex

Hi Dan, I can see where you've reached your conclusion, but your comment that "Rudy seems to say..." is a good qualifier. Let's get back to basics, say with a classic 1/4 WL vertical. The theoretical
