Excellent summary, thanks for posting. Which did you decide to use? I just noticed a similar leak in our unit during very heavy extended rains (like at the end of 48 hrs of raining), and it was a very slow leak. I took a look up there when I got home, and I'm wondering if the leak is not where the mounting plate meets the roof, but rather where the coax goes down into the base. There was some caulking in there, but not much. Pooled up in there long enough, I'm wondering if it eventually soaked through. I don't know exactly how that antenna is mounted, but if that's the case, you could end up removing the antenna and reinstalling only to have the leak continue.
