I've never had a front-end die due to wind/rain static.

However, I've lost the SWR diodes in THREE different units - a Ten-Tec
509 Argonaut, a Ten-Tec 405 amplifier, and a Drake W4 wattmeter.

In all three cases, the "offending" antenna was a cushcraft 40-2CD 2 element
40M yagi, which has a non-DC-ground feedpoint (basically just a dipole
fed from a coaxial coil balun).

Needless to say, my QRP+ doesn't get anywhere near that antenna!
