[Elecraft] static charges

[Mike WA8BXN]

The first thing that comes to mind is a switch that would ground the
antennas when you disconnect them. Next thought is a path to ground when you
are using them or not. That could be an RFC (Radio frequency choke) to
ground or perhaps a resistor to bleed off the charge. Use of grounded
antennas may be another possibility. That might be a loop antenna that is
grounded at one end. Another could be a vertical with a matching network
that provides a ground path. A description of the antennas that you have or
intend to use would be useful to provide more specific suggestions!
