If you decide to go with a non-weatherproof connector, here are ways to weatherize it...
- Self-fusing rubber tape: best.
- Regular electrical tape: not so good, but it helps.
- Silicone: works well, but a bit messy and hard to remove.
Outside weather connections:
For lots of years I have used ignition silicon grease
for cars (insulator for moisture on spark plug wiring) on my company outside R.F. electronics. Tubes at a car store.
Just assemble your connector as usual (I prefer the Good RG6 crimp ones, and then squirt a gob of silicon grease the size to fill the open end of the male connector and assemble to the female with a wrench to tighten.
We use this technique up to 10 GHz and have excellent results over many years.
When you try to seal a connector you will accumulate moisture inside the sealed connector when the temperature goes below dew point.
You will never have a gas tight seal with tape. That is why better systems at high frequencies back-fill with Nitrogen dry gas to keep out moisture. The grease makes it impervious to moisture.
Also the dielectric constant for this grease is so low it doesn't foul up the impedance matching. Little loss.
