1) How to feed the antenna and be able to run legal limit, all bands?
Put your matching network at the base of the antenna. Feed your matching
network with coax.
Thanks for your reply to my message, but this is not feasible. The
antenna is 120' from the shack, unblanaced transmatch in the shack.
Looking for matching network at the base of the antenna ...
This is what I suggested but it will have to be switchable or tunable
for each band, maybe a stub for each band. There is no single fixed
network or balun that will do the job. The impedance on some bands
will be sky high and cause sky high SWRs on your coax.
(or apex,
maybe), perhaps balun (???), but needs to be broadband so antenna can
operate multiband.
