Hello again. My B19 has the crank and roof mount, but no antenna. I would not use it even if it was there.
Would it be worth removing it (as a potential leak source down the road) and patch, or just pretend it's still there, and regularly reseal the edges, since I have to go up there and do that to the other openings every year anyway. The seal is sound, and I have no
leaks.
I suspect that it might be more trouble than it's worth to remove and patch. It wouldn't be high on the current list of things to do, either way, but just a thought when I was checking out the roof yesterday.
Other possibility - replacing the antenna. I haven't had a good look at the remaining mount. It may or may no be functional anyway. But does any one know where I might source a replacement, if everything was functional, and I decided to go that route?
