I still have my training wheels on, but I am trying to model the subject
antenna, as described in the ARRL's Antenna Classics.

The feed end at ground level calls for a 9:1 transformer. The opposite end
(also at ground level)calls for a 9:1 transformer with a 50 ohm dummy load
attached. How would I include these in the model?

Thanks for your patience and help.

Bill
