<John,
<I don't understand the "draining" technique just by looking at the sketch of
the antenna but know from experience that water sealing sometimes result in
accumulation of water there it doesn't belong. That's what drain holes are for.
<A tips though, I usually flood my connectors with VASELINE just to make sure
there is no room for water. I've seen the phone companies do that to prevent
corrosion on their connectors and also worked with outdoors cables that have
VASELINE inside. Very, very sticky but seems to do the job. A <thin layer of it
doesn't seem to cause connection problems as you might think. I don't know if
the connecting part is pressing through it or if a thin, thin layer is
conduction. I have heard both theories.

## Vaseline is a big no-no. Its a petroleum product. It also liquefies at
just 100 deg F. None of the telcos ever used it, and still dont. I worked
for the Telco for 34 years. If I ever caught anybody slopping vaseline on
anything, they woulda got a boot up their rear end.
Flooding a coax connector is not recommended. What does work is to use a TINY
layer of dielectric grease, like dow corning DC-4 or DC-5 or most other
versions of dielectric grease on the center pin, and also the threads. You
can also apply a thin layer of dielectric grease
to the red silicone rubber used to water proof Type N connectors.....and
ditto with a 7-16 Din connector. You can also use a thin layer of dielectric
grease on the rubber gaskets used on NEMA type 4 water proof boxes.
