Solarcon A-99 CB Base Station Antenna Waterproofing

[Unidener]

For storms, I would like to be able to remove the antenna and leave the base mount.

Is and what kind of waterproof connector could I put on the base after removal?

Thanks for any suggestions!

The A-99 is comprised of 3 sections..6' each one. The lower section incorporates the coax fitting. There's no base to remove. Two things that I would recommend for users of these...replace the two split type lock washers used at the joints and replace them with inner star washers. The other is to either use the ground plane or use a few snap on ferrites just below the coax fitting. I've always used RG-8X coax because I have very short coax runs and snap ons with 1/4" ID fit perfectly with just a bit of squish.

But it looks from videos the sections ALL connect to a to that. What I'm asking is there a terminator or something I can put on it while the antenna (white sections) are removed?

The aluminum tube that the mast clamps to also houses the coax connector...and the first 6' section of the antenna...at least on every A-99 that I've ever seen or used. I don't think there's any similar antenna constructed to separate like what you're describing. Only antenna type that sounds like this is a screwdriver type mobile HF antenna that ties together with 3/8-24 thread connectors. You can remove the coil and whip and leave the base behind.

I may have left out that I live on the coast.....that's why I'm so concerned. Some storm rain contains salt
I just got the antenna a few minutes ago....I'll try to figure out some kind of cap with some dielectric......sound plausible?

If you're worried about water infiltrating the coax connector, find some liquid electrical tape at the auto or marine supply store and apply at least two or three coats. Just cover the lower threads and the plug. Don't fill the tiny hole that's up inside the aluminum tube...it lets moisture drain out from inside. When using LET, be sure to stir it thoroughly to get all the vinyl goo well mixed. The great thing with LET is that it can be removed cleanly with a sharp knife. Most other sealer leaves a horrible mess.

West Marine has it and now after thinking about this, I believe I have some from repairing an underground sprinkler wiring.....put on years ago and no issues yet?

Will test it out on some car mount antennas and see what it's like and look for side effects .....

Thanks....could be my answer I needed!

Older cans of LET tend to dry up and harden. You may find that you'll need a fresh can. Usually auto parts stores also stock this stuff.

EDIT: After thinking about what you said....I had some putty rope (OK for outside) that I already had (pack rat)! Thanks for saving me some $$$!.

There's another goop to seal taped electric splices I've seen it used to final coat a connector. I forget what its called, it was a fast drying rust colored goop. It totally degrades in sunlight.

I also got some of the silicone self bonding tape!
