The capacitor value is OK, but disc ceramics do handle current well.

Subject: Topband: Antenna Switch isolation capacitor
Hi All,
A friend on 160 has had a problem with a Heathkit remote antenna
switch
due to a partial failure of the isolation capacitor in the remote
unit.
It is a .02 uF 1.6 KV disc ceramic that isolates the DC from the
antennas.
Since this results in about 4.4 ohms of XC - capacitive reactance in
series with the 160 TX antenna, I was wondering if it would it be
worth
while to substitute a .05 uF disc ceramic to reduce the capacitive
reactance (XC) to under 2 ohms on 160 meters?
Thanks any info. 73,
George, K8GG
