I'll second the polyphaser as a good product. We put it in a POP in the
base of a 460 foot tower and the equipment and it survived unscathed for at
least 5 direct tower lightning hits that we know of since 1998. There
were
13 DS1's that sometimes popped fuses at the demarc during a strike. The
Polyphaser stuff protected but the hits were never big enough to cause it
to
fail in a shorted state after strikes.
They have a web site
http://www.polyphaser.com
It must still be installed according to proper engineering principles
for best protection. They have some great engineering references on their
web site.
