I'm building a high power remote antenna tuner, which
will be used to rough-match 50 ohm coax to open wire
line from an 80 meter dipole (possibly extended), on
160-10. Beam won't go up until Spring, at earliest.
The tentative plan is to use relay switching between
preset tuning positions for each band or band-segment,
and to run the coax at 2:1 or less. This will keep me
in range of the shack auto-tuners.
All the posts I saw on the topic of relays dealt with
an essentially matched situation, and high power. At
least potentially, I'll have high voltage to deal with
on the high-Z side of this matching network.
Would anyone care to wade in on the topic of appropriate
relays for switching taps on the inductor, or switching
Anyone got a source for vacuum variables which might be
appropriate in this application?
Random $.02 welcome.
