Generally the coax runs in 3 parts.
1: From antenna to roof, at this point there will be a connector.. NOTE: This is the part of the coax that goes bad. The rest of the coax should last the life of the coach....or longer.
2: Roof to switch (Wall plate or box of many buttons) IF you pulled on it you MAY have damaged it.. but if you still have proper continuity then it should still be good.. Comments explain.
3: Switch to TV.. See above remarks.
Pulling can pull it out of the connector crimped on the end.. Does not take much to do that. I'v had to repalce a few of those in this coach.. I use a much better replacement. (Compression fitting).
Second. What "Wears out" coax is sunlight.. Inside the wall there is no sunlite, Inside cabinets there is no sunlight. only the cable roof to antenna gets sunlight.
Home is where I park it!
