The feedline runs straight down the tower to a PolyPhaser grounding board and runs thru a ICE protector and then into the house to the repeater. The run down the tower is 40 ft and then another 10ft into the house from the lightning board. There is no loose coax flapping in the wind or anything like that. All connectors are sealed with Andrews coax seal kits. It is not possible for me to run a new feedline just for a test. Thanks for the input. I will start checking the connections on the grounding board and everything I can get to without climbing up the tower. I have to start someplace. dan
