Scriv, We always do the same thing and we have never had water issues. It is a simple way that a local HAM guy taught me.
1. Hand tighten the coax to the antenna 2. Wrap with 3M electric tape from bottom of fitting/heat shrink up to the base of the antenna (in that direction as it acts like shingles on a house) This wrap not only helps insulate against water, but enables you to get the mastic off easily if you ever need to un-do the fitting! 3. Wrap with a good gummy mastic tape making sure to push the mastic in the voids above the coax where it meets the antenna. We use this; http://www.tessco.com/products/displayProductInfo.do?sku=53051&eventPage=2 4. Then completely cover the mastic a couple times with the 3M electric tape again - starting at the bottom working toward the top. This wrap keeps the mastic from melting and dripping off during hot weather. Do not use the cheap vinyl electric tape as it will not endure the weather.

I have a problem that I would like to see fixed. It seems that after every long rain we see problems with the occasional connection outside at the antenna getting water into it. We use the Scotch seal mastic tape to seal the connections. The guys do not like having to climb and they work hard to try to make sure we do not get these problems and yet they come back. I would like to hear what you veterans out there are doing to make sure the water stays out.
