Just to start an argument, why is it that EZNEC shows zero gain

for a vertical antenna in the horizontal plane? Whereas, all your
diagrams show maximum gain along the horizontal.

EZNEC shows the same patterns/gains as in the plots I posted,
when its models are set up correctly.

========================================

The model for a simple vertical above ground is simple enough.

Perhaps YOUR way is incorrect if the pattern disagrees so strongly
with EZNEC.

Reg,

My models agree with theory and measured results, as have been developed and
well-proven for 60+ years in the broadcast industry.

If you doubt my plots, why not send them to Roy Lewallen ask for his
comments? You might also ask him to tell you how to model these
configurations properly using EZNEC.

I'd explain it, but probably that wouldn't be acceptable to you (plus you
didn't ask me).
