[Elecraft] PA storm damage

FWIW I use a Coax arrestor in the main feeder right at the antenna selector 
switch in the garden, *and* wind the main coax feeder into coils of two 
turns approx 1ft diameter before the feeder goes underground at the switch 
end, also at the house end right after it surfaces. For open wire lines new 
sparkplugs. The "ground" at the selector switch end consists of a collection 
of bonded metal "things" buried in a trench about 2ft deep, using 1-1/2 inch 
flat braid for ground connections. This arrangement protected my receiver 
when one of my 40m vertical dipoles took a lightning sideswipe which hit two 
or three years ago not during a local thunderstorm although there were dark 
clouds nearby, which disturbed the soil around the grounding braid's path. 
It was a flash - bang - buzzing noise event :-)

73,
