Hello Fellow Tower Talkians, I'm placing a 65 ft. tower with a C31XR on top, approximately 400 ft from my shack in the house. I've always used RG-213 or RG-8U in the past to this Yagi, (but I've never had the tower that far away before either). Anyone see a problem continuing to use the same coax with that distance? Thanks, Tom K8ANA
