It sounds like the model of the pickup was inadequate -- it's at least
as important as the vertical. How did you model it?

From the responses I have gotten, that is the problem, I didn't model
the pickup. I wanted a simple way to determine the L I needed to get
the antenna resonant. I don't think it would be worth it to try and
model the truck just to get that small amount of data. By the cut and
try method I have determined the inductance I need is about 70% of the
value I get on EZNEC. I guess that is not too bad, gives me a
starting point. Thanks for the responses.
