coaxial cable roof penetration: no cable entry plate beware leaks
Posted: Thu Aug 11, 2022 7:58 pm
Friends and countrypeeps,
For the five years I've owned the Turtle, I've noticed a musty smell in the closet. It's a 1996, so no wet bath but it has the black tank vent stack running through the closet. I've always thought that maybe there's a little leak in that. But then I realized that the smell was not sewer gas, but rather musty or mildewy, and probably indicative of a water leak.
I checked the roof on the rear passenger corner and the seals where the roof rack/antenna are mounted seem sound. However, at the penetration for the coax TV cable there was a problem. With no cable entry plate, the cable just ran through a hole in the roof into the van; it was sealed with a rubber-type sealant. But the cable had come loose of the sealant so any water that got on the cable could conceivably run down the cable into the van--in back of the 12v and coax connection plate above the stove. Others have noted that this can short out that connection.
I will soon be taking out the back panels in the closet (after Burning Man, because only so much time!) to see the water damage. But meanwhile, I pulled through cable for a cell signal booster, replacing the old coax with new, mounted that antenna aft of the A/C unit with a locking hinge https://www.amazon.com/gp/product/B08G4 ...
