When the plate blocking cap fails, this puts the HV across the antenna
terminal.
The purpose of the safety RF choke is to trip the primary CB's or
fuses to
remove the HV from there WITHOUT destroying itself. If it is not
robust enough
to take the "hit" and fails open, the lethal HV is STILL on your
antenna!
(Not good!)
