[R-390] Grounds

[wli]

All: many thanks for the many responses to my original query re the metal roof and my vertical. I was thinking of a RF ground.  As noted, braid is probably preferred for that function.

Living at 500' just east of Seattle, we rarely get lightning: it mostly happens in the foothills 25 miles east. If and when we are warned about a local thunderstorm (a rare occurence here), I just disconnect all the gear from the antenna system, (and get down on my knees).

Thanks
