We have since purchased some polyphaser surge protectors.
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.
