I need to replace the coax from the Wineguard antenna on the roof of a 2003 38G Suncruser . I was hoping there was a F connector on the base of the antenna on the roof top but it looks like the coax goes through the antenna base to get into the coach. Has anyone replaced the coax to the antenna? Is there a connection point inside the RV to connect to replace the coax that has been cooked in the sun?
