I received this note from Phil Bankston - my next door neighbor who has
experienced this location for longer than anyone in the neighborhood.
"I know the strike you are speaking about. It wasn't a direct hit, but it
was a damned close one. I happened to be looking out my front window, and
it was extremely close. I checked all my electrical and electronic stuff.
No problems, but that is because I have more lightening protectors than
anyone in Deltona. Good ones -not from Wal-Mart.
When I first came here in '78 I had just gotten my first quality stereo and
accessories in when a strike hit a tree just across the canal from me.
Over the next three months all my new appliances went to hell. Only my
stereo was undamaged. The reason, a set of quality arrestors was installed
on it. The doggoned stuff cost me more that my refrigerator!"

The five coax lines are buried in aluminum down spout tubing. I'd have to
dig it all up to inspect it. If/when I determine an unacceptable VSWR, I
can isolate the underground part from the run that goes up the tower. At
the base of the tower I have another single point ground plate where all
coax lines go through the plate via coax barrels/ feed throughs. That also
helps those surges that are on the braid find a shorter path to ground than
to come into the house to do so! I've been tempted to add another set of
Polyphasors at that point as well!
