Roof Mast Antenna

[LABergo]

I have 3 mast antennas on the roof of my 2007 Mountain Aire. All are on the passenger side, one forward and 2 mid coach, over the entertainment center. I assume the forward one is for the dash stereo and the 2 mid coach are for the FM reception for the receiver in my entertainment section and FM reception for the outside entertainment center. Are these assumptions correct?

And, all 3 are broken and need to be replaced.

Yes, your assumption is correct. If they are the short "rubber ducky" antennas do a search in this forum. They and available replacements have been dicussed. I've replaced all three on my 2007 coach in the last year due to breakage. I think the root cause to the breakage is weathering. The rubber cracks from oxidation, then water gets to the inner metal winding and rusts it, after that they just break and fly off running down the road. The last one on mine I found the detached section wedged at the front of one of the roof air units, after examining this is what appeared to be the cause.
