Itasca Sunova TV antenna Coax problem

I just went through this on my TT. My cable was spliced under the antenna (Winegard Sensar) on the roof with f-connectors and a barrel connector. I was able to get enough pulled out (about 6 inches) and replace the ed on the cable under the roof, put the barrel connector back and run a new cable up the mast to the antenna. That took care of it for me. Try to see if you can find a splice under the antenna to replace.

I put a Jack Antenna on it and it's so much better.
