Bread slicers have their issues and are not really the best solution.
Herb, I must agree with you. Over 25 years ago, I tried to shunt feed my tower.
I had a very heavy duty "bread-slicer".It tuned fine. But when I put power,
1500 watts, to it the plates warped. I changed to a couple of Vacuum Variables,
500pF @ 7.5kV and everything is fine. The tuning has never changed. I set it to
1830kHz @ 1:1 vswr and the 2:1 bandwidth is ~ 40kHz. 73 de Price W0RI
