Why not an autotuner at the antenna feedpoint?


Too much money.

Anyway, eventually (not right away) this antenna is going to be used
in an ALE network and I rather doubt that autotuners work very well in
that kind of an environment.


Anything over about 90 feet should work. 125 would be just about perfect.
And no, they DON'T have bad spots....usually they stay under 2 to 1 across
a fairly wide band and efficiency stays good above the knee frequency.

Model it, if you want exact performance figures.
