Standard practice with some cable TV systems here in Ontario is to use 
Vaseline-brand petroleum jelly as an aid against water intrusion & corrosion...

Here, with my "L's", I use ordinary PL-259 / SO-239 coax connectors at each 
base: I apply Vaseline to the prongs of the PL-259's, and swab a bit onto the 
threads of the SO-239's , before mating them. I then apply a VERY generous coat 
of Silicone !! sealant all over the pair, well beyond the end of the connector 
& on up the coax cable...

Come Spring, when it's time to stow the antenna, I simply get an X-acto knife, 
make a longitudinal cut into the silicone (being careful not to cut TOO deep), 
then peel off the silicone...

I've done this for some 6 years now, with nary a problem with water 
intrusion---and the connectors come apart just as easily as the day that I 
Vaselined them...

Call the technique "red-necked", or "hillbilly", it works for me---and it uses 
cheap, readily-available, material...
