I have been noticing the SWR on my IC 7300 has been acting strange.....I thought it was problem at feedpoint on my G5RV......So today I was painting my deck and thought I would check the coax from the HF antenna to shack. I have a G5RV up in an old pear tree in backyard. The ladder line runs straight down tree to a junction where coax connects. The coax is buried (buriable type) about 27 feet from base of tree to edge of deck. Its buried just a few inches. Where coax comes back up from under ground, It was run along side bottom of deck to edge of house, then up side of house and into my 2nd story shack. So anyway, thats the scenario, and when I checked the section next to bottom of deck I saw a GNAWED PORTION of coax, about 2 inches. Could be rabbit? Squirrel? So I had to rip it all out, and ordered a new 60' length of same coax. But this time I will secure it with coax holders, those little plastic things with a short nail, right to edge of deck off the ground. Then cover the whole length along deck with 1/4" rabbit cage wire. When I originally installed the coax I didnt think animals would chew it. But there must have been rabbits or squirrel under deck. So I gotta vermin-proof there too.
