Jerry, you have opened up Pandora's Box.
This subject has been discussed over and over again on the reflector.
While I just came back on the reflector yesterday from several years of
absence, I recall this issue from about three years ago.

Anyway, my opinion - Never install aluminum vertically (towers), just
horizontally (antennas).  Lots of reasons why.  It is a serious risk you are
worried about losing the tower and any antennas on it.  It's more
serious if there are houses, cars, people within any drop-zone around the

Aluminum tower owners will differ...

Bill, N3RR
