Anybody ever tried this on a 5/8 wave ?
You've got a tuning coil going from the ground plane to the vertical element.
Normally you would run the jumper from the center of the coax to somewhere along the coil to get a 1:1 match on the frequency you want to tune the antenna on.
What if you ran two pieces of coax up to the antenna and took 2 taps off the coil?
In my case I would tune one of the taps at 28.4 for 10 meters and one at 27.205 for 11 meters. That would allow a 1:1 match on two bands.
You could use a switch at the radio to switch between the two pieces of coax.
Would that work or would the two taps interfere with each other?
