Hi, Everybody,

A short vertical such as for mobile use is capacitive and this Xc is usually
tuned out with a shunt coil at the feedpoint. Yet, when I model this with
EZNEC I cannot simulate this effect properly. I must be doing something
wrong. Does anyone have an EZNEC example showing a shunt matching coil
inserted as an EZNEC Load at the feedpoint that they can send me?

Thanks very much.

FWIW, I use the information provided by EZNEC as input to the TLW
program (ARRL Antenna Book) for this set of conditions.

Note that radiation from the matching device is ignored under this
circumstance.
