Damaged Roof Antenna Mount

Howdy Campers,
I recently returned home from a short outing in my new (new to me) 2008 Shamrock 21SS and noticed a sharp bend in my roof radio antenna. I believe it was caused by low hanging tree branches encountered on our rural Colorado dirt road. Upon closer examination I believe the mount underneath is torn loose in the front and is only being held in place by the roof membrane. Not good...I know! Anybody else ever experienced a similar problem? Any suggestions about how the mount is attached under the membrane and caulk would certainly be appreciated before I create a bigger mess than I already have. Thanks in advance.

Most likely it's just screwed into the wood panel of the roof. It probably has 3 or 4 screws. You'll need to remove the sealant around the antenna base. Clean the area and check the holes to see how much wood is really there. Most likely it's about a 1/4". There are wall anchors that could be used in the holes to secure the antenna better. Does that antenna have a spring look to it at the bottom? If not I'd recommend locating one to replace the straight type. They are way more flexible. Reseal the entire mount with the Dicor sealant that you pour in place.

Camping World sells it and it's available at most RV Dealerships.

It's a regular automotive antenna. The mast is screwed into a base or flange. The flange is fasted to the roof with wood screws. I quickly updated mine as one of my first upgrades when I brought my trailer home the first time. I bought a rubber, black, car antenna with signal boost. I also picked up some self leveling caulk/sealant. After pulling off the old caulk, I found the wood under the rubber membrane was a little water damaged. Being glad I found this sooner than later I planned to use alot of sealant under the flange, on the screw holes and around the joints and mast. It looks cool, but the poor quality concertone did not tune distant stations any better with the signal booster. Pointless in my situation to use the signal boosted antenna. My only recommendation is that you use regular wood screws into the roof deck. If you use something like screws and nuts, the next time you run thru low hanging branches, the decking may get torn up or the antenna will get busted.
