GM4ESD also suggested this and I am going to try this, since it will
require the least modification to my existing antenna. I will build up
the circuit on my bench and adjust it for the reactance shown by EZNEC
with my MFJ analyzer. Then I'll hook it up and make final adjustments
on the antenna. It will be interesting to see if the antenna appears to
perform better.
