We installed a small outdoor UHF antenna yesterday for HDTV signals, and ran a 50' RG6 cable into the house. Yesterday I noticed our old surge protector was used up (protection light was out) so I bought a Philips surge protector at Wal-mart for $32. It has connections for 2 coax sources, but the instructions say that the unit will protect coax (cable?) and broadband lines, and not DBS products like antennas or satellite dishes.

I don't know if this is true, but I imagine Philips would deny coverage if lightning were to hit the antenna. Amazon has a Tripp Lite for $33 (sorry, it won't let me post a link). Does anyone know if this or other similarly priced protectors cover antennas in their protection policy? Thanks

Take a look at Panamax, they make the best overall surge protectors.

The Amateur Radio guys are experts at isolating equipment from their lightning pole antennas. You could ask some of them at www.eham.net

There are some vendors that sell stuff that can handle some pretty significant antenna based surges etc.

Good luck!
