In the case of your 110 foot flattop with it's 110 foot feedline and
for my specific purposes the "tuner" would be a pair of inline lo-loss
fixed coils with taps which are selectable with a simple two pole
two-position ceramic rotary switch. Or make it a three pole switch and
be able to ground the antenna. Three taps yields three slices, etc.
Or use relays. Switch the 50 ohm end of the coil to avoid high voltages. Two
relays yields four possible choices....
A
tuner like that would be a whole bunch easier to build and use and
would require much less mechanical claptrap than the original pair of
variable caps scheme requires.
Perhaps. An old electric screwdriver could be used to drive a pair of caps or
rollers, too. They're all over the place, discarded when the batteries go bad.
