I too apply medical grade petroleum jelly (i.e. Vaseline brand) to all my
outdoor connectors ever since I read about it in ON4UN's book. On
the common coax connectors I completely fill the space where the braid
is soldered, move the "shell" toward the end, then fill the end of the
the jelly....THEN screw the connector on the coax fitting, letting the
weep out. If the coax covering has been screwed in tightly (as it would
with RG213, etc) IMHO there is no need for any further weatherproofing
unless the connector is hard to get to. I replace the jelly occasionally
during routine maintenance. I've never had a problem with water getting
in the connector or coax.
