My top-loaded vertical needs a series 260pF capacitor at the feedpoint to
match the 53 + j335 impedance (1.825 MHz) to my coax feed.
I have a few different air-variables I could use, but I was wondering what
sort of fixed capacitors would be suitable in this application.
Max power is 1500w. I
Jon,
There are ready-made place for TB , with TX antennas .
It is necessary to organize the good RX only .
I used VK5ZVC coaxial loop and preamplifier AMECO PT- 3

Thanks for the cap suggestions everyone, and for the V and I calculations
Tom.
Ideally I'd like the 300pF (or so) vac. variable and so will watch for a
decent deal on one.
In the meantime, I will parallel four 50pF doorknobs (7500v and 1.8A at 1
MHz) and single 100pF variable with .05 plate
Still needing T88 on 160, I noticed this this:

If a ham lands the job, I'll mail some wire for Topband :)
