Receive antennas - damage potential

[Ken Kopp]

I severely damaged (burned up!) the receive antenna input board of an
FT-1000D once due to excessive input signal from a near-by transmitting
antenna.

Once was enough ... installed small shorting reed relays on all receive
antenna inputs on all radios in my (then) multi-op contest station.

Regarding "St. Elmo's fire" ... Was a marine R/O for some years, and
often saw / heard the entire ship ... especially rigging ... "glow".

Grew up in dry, windy Oklahoma and often heard the snapping of
precipitation static discharging inside rigs.

I recall marine transmitters that I sailed with having big resistors from
antenna to ground to prevent static build up.  An old hand told me they got
warm when sailing the Indian Ocean.
