I have a number of, quote, "High Voltage" reed relays. They were made
by FR Electronics (as was) and I seem to recall are specified to
something like 10kV and 1 Amp which means they may well work higher if
not hot switched. They were originally intended for use in automatic
ATUs intended for frequency hopping radios.
They're hopefully still buried in a box in my storage shed, but I'll
look them out and can pass on to anyone wanting to experiement with
loading coil switching. Coil voltage is 24 V but with everyone using
MOSFET PAs these dyas I'm sure that won't be a problem.

The other factor is that my station is not optimized on receive on
136k when working crossband because the antenna is tuned to 72kHz.
What I need is a relay that will short out the 72k section of the
loading coil on receive, so the contacts have to stand many thousands
of
volts! When this problem is sorted out I am going to try a cross band
