Bob W7RH - you don't need expensive hard-to-find vacuum capacitors to
match a quarter wave 'L' or 'T' on top band. I use cheap multilayer high
voltage disc ceramics and these have been working perfectly at QRO levels
with my inverted 'L' for years.
I use 1600pF made up from 1000pF + 470pF + 220pf all rated at 6.3KV and
available (over here) from CPC at less than $4 for 10.
Antenna is slightly longer than a quarter wave so it is inductive and the
capacitors form the other part of the L-match network.
