OK, this is OT, sort of. It will be connected to my K3 so..
I just bought a remote mast mounted antenna switch (Ameritron RSC-8V). It comes
with the center conductor electrically floating when the port is OFF. It seems
to me I would be better off (safer) if the center conductor was grounded (or

Clint,
Not OT at all. Many remote antenna switches do it the easy way, and
use SPST relays to switch in the selected antenna - there is no way with
that type relay to ground the antennas that are not currently selected.
So yes, some type of static discharge device would be beneficial across

If you want to see a remote antenna switch that grounds all un-selected
antennas, take a look at http://www.qsl.net/ei7ba/remote.htm
It is quite easy to homebrew your own remote antenna switch.

Don makes an excellent point. And a really cheap and effective way to do it
is to put a resistor from each antenna hot side to ground. For a 50-ohm
transmission, 500 to 1000 ohms is fine. That will bleed off any charge
building up on the antenna but will be too high of a value to affect the
