Short answer to the original question: YES, but not often
More likely .. Over time the coax cable (roof to head) goes bad due to effects of Sun and Weather.. The connections also tarnish and loose contact
replacement every decade or so is (Possibly far sooner) is indicated, also when you disconnect treat the connections with DE-OX-IT or better yet DE-Ox-IT followed by De-Ox-It Gold.
There is a connection in the roof, mine is under a "Clamshell" plate... That was toast on my RV, had to remove connector, replace the cable ends with a better ones and put in a new connector as well I mean it was in sad shape.
That is my #1 suspect in fact.. Took ma a good amount of time to scrape off the Dicore,m unscrew, lift and seperate then about 1 second to inspect, a few minutes to renew the cable ends and replace the barrel then it was put it all back together time and seal far better than factory did.
