To model this in EZNEC I put the source in the lowest current segment. The
ground loss R can be in the next segment. The shunt inductor is olaced in
the lowest segment as a load with *Ext Conn* set to *Par*.
Alternatively the antenna can be modeled with 1' current segments with
the source placed in segment 2 from the base. Add a square loop across this
segment. It is constructed with three 1' segments. Place the shunt inductor
in one of these three segments.
