I second this suggestion. I use
Polyphaser arresters, and have been quite happy with them. You’ll know
when they “take a hit.” <wink> I also have some questions for the original
poster, though. You mentioned that the antenna is “about
27m up on top of the building”. Did you mean 27 FEET? Afterward you
asked about a rusty tripod – I don’t think they make them 27 METERS
tall. <grin> Did you replace an older repeater? What
brand did you settle on? Finally, why didn’t the department budget to
replace the infrastructure along with the repeater? Just curious. Mark – N9WYS From: Just so you don't have to spend more money on a new repeater after a
few thunderstorms, a lightning arrestor is a must. A polyphaser is the arrestor
of choice on our systems. The old feedline could be the problem as far as your
coverage problems go. Some things to help determine what you problem might be are: Is there any desense between your TX and RX? What kind of antenna are you using? Terrain issue maybe? Also I would see about measuring the power out of the coax at the
antenna end and do a quick calculation on what your losses are. For a VHF
repeater, 1/2" Andrews Heliax is a pretty good choice for VHF for the $$. Andy Yahoo!
