Hi All, Sorry if this has been beat to death, but I searched the archives under radials and pattern and thousands of articles turned up at once. Way to course of a search. I'm working on my ground sy
Hi Tony -- EZNEC 3 is not capable of modeling radials at 3-inches above ground. A 3-inch separation between ground and radial is below 0.001 wavelength at 160m. Even with NEC4 one should avoid modeli
Tony There must be more to it than that. My vertical has a nearly circular pattern, maybe 0.25 dB "front to back ratio". The vertical is at the center of one edge of a rectangular overhead counterpoi

EZNEC 3 is not capable of doing the necessary ground model mathematics to adequately model your antenna. EZNEC Pro/4 shows much less variation than you are showing. If the woods are dense, can't you
Hi Tom & all, Thanks for the input, thought provoking as always. I neglected to mention that the model I'm using is a short 46' vertical with a 120' T wire for a top hat running along the x axis. I m
I regret disagreeing with my friend Earl, but I just purchased and installed EZNEC 4, and it, like EZNEC 3, uses the NEC-2 engine. EZNEC 4+ offers more segments and a few additional features, but als
"EZNEC 4, and it, like EZNEC 3, uses the NEC-2 engine. EZNEC 4+ offers more segments and a few additional features, but also utilizes NEC-2." == My mistake. Dean, N6BV said that he was using the NEC-
