I was thinking it may be nice to have a tuner that could control an
external relay to switch in/out custom networks for adapting it to
site specific operating conditons.
Why even have a tuner if you are going to switch the length
of the feedline?

In my Arizona implementation of this antenna, I used
relays driven by a 80C51 microcontroller to achieve
an autotuner function.
