Hi turkey,

On our rig, if you disassemble the rotating antenna handle in the bedroom, you can reach into the opening and fish out the coax. The piece coming in from the roof is joined to the piece that goes to the signal booster by a barrel connector. The connector may be loose, or the coax connectors might need to be replaced. Doubt the entire cable needs to come out.
