Toss the antenna if it has an SO-239, and like you said, use hardline with a N connector. Buy an antenna with an N connector and use proper install and weatherproofing techniques and forget about it. Too much wasted energy and time screwing with the stuff you have now. That had proper weatherproofing on it. As best I could do. It was mostly done on the ground and then the antenna attached to the mast was inserted into the lower section of mast that was existing. Don't know how to do a better job without encapsulating the entire thing is rubber. But yes, if I have to go up there to strip it down new coax and antenna will be on the list. This was only up there since about June. Could also be infiltration at the lightning arrestor. But that is an N fitting on both sides. Still wrapped to death. tcp2525 1 Quote

I’m not even sure that what you did is related to the problem. You might end up replacing the cable or part of it but you can sell the antenna or change the connector at the feed point. Quote
WRXL702 Posted Thursday at 09:24 PM Report Posted Thursday at 09:24 PM N Type Connectors Are Not Sealed, Nor Are They Sealed Any Better Than Any Other RF Connector Used In An Outside Application. Grease On The Threads On A Coax Connector Has Nothing To Do With Preventing Moisture Ingress. They Are A Running Thread, Not A Pipe Thread, Therefore A Grease Compound Is Not The Solution For Proper Outside RF Connector Waterproofing. Proper Wrapping 1st With A Quality Butyl Tape From The Bottom Up & Then Covering With A Quality Electrical Tape, Again From The Bottom Up Will Ensure Proper Moisture Ingress To An Outside RF Connector.

As others have mentioned, the SO-239 isn't sealed like the N connector. And no matter good a job you think you did with weatherproofing, it is still very vulnerable to water. In my opinion, if a UHF antenna has an SO-239 it is crap. I would be curious to as what you find when you pull it down and inspect. Good luck with it. Oh, and I never did find out what antenna you're using. It's possible the antenna radome is compromised. Quote

Have you ever seen an N connector? If not, you might want to reevaluate that statement. I'll take a properly installed naked N connector over a totally wrapped PL-259/SO-239 any day of the week in the harshest weather. WRUE951 and SteveShannon 2 Quote

I'm perplexed as I don't understand why the manufacturers wasted all the effort and materials to put a gasket that seals the two mating connectors. Had I known they lied to me and charged me more for an N connector I would have just made a Western Union splice in my coax and called it a day.. SteveShannon 1 Quote

But it is something to consider. I really haven't noticed much difference with my Comet GP-9 or CA-712EFC but I do see a change with the MFJ multi band vertical HF antenna when the temps get really low. The change in SWR on the MFJ is not as much as with the cobweb but still noticeable. Food for thought. SteveShannon 1 Quote

I don’t recall anyone suggesting they shouldn’t be wrapped, but Amphenol sells them as weatherproof and even has N connectors listed as suitable for extreme exposure. https://www.amphenolrf.com/rf-connectors.html?applications=638350 WRUU653 and WRUE951 2 Quote
AdmiralCochrane Posted Friday at 03:39 AM Report Posted Friday at 03:39 AM Just like the threads of a flare nut not being the sealing surface I understand that the threads of a coax connector are not watertight seal areas, but I am of the persuasion that some greasy material in the middle of the connector short of hydraulic locking the mating surfaces from making contact is beneficial as water, can't occupy the same space that something else already occupies. Water can easily displace gases like air, but has a much more difficult time displacing oil or grease. SteveShannon and WRUU653 2 Quote
LeoG Posted Friday at 03:51 AM Author Report Posted Friday at 03:51 AM Well looking at a set of mating N connectors it looks like the mating surfaces are the flat area of the female and the rubber base of the male. If you put a small coating of dielectric grease on the female flat mating surface it looks like the internal portion of the connector has an excellent seal from anything penetrating it. The only ingress would be from the rear of the connector using capillary action into the fittings. Water getting in through the threads should have no chance of getting inside the fitting if it has been tightened properly. AdmiralCochrane, WRUU653 and SteveShannon 2 1 Quote

LeoG Posted Friday at 01:30 PM Author Report Posted Friday at 01:30 PM Hit 32º at 5:19 this morning and it's 8:30 and 36º currently in my backyard. So plenty of time for any ice in my coax/connectors/antenna to liquify. My SWR is at 2.08. I don't have full quieting with my repeater currently and the Holyoke repeater is at 1/2 scale instead of full quieting like it was yesterday during the cold. As always the other 2 repeaters are full quieting. I'm starting to see a trend. Quote
LeoG Posted Friday at 01:34 PM Author Report Posted Friday at 01:34 PM And correction on my coax type. I do have LMR400 at the shop, @50'. But at the house I have M&P Hyperflex 13, @84'. A 60' section to the lightning arrester and 24' from there to the antenna. Lightning arrester is type N connectors. SteveShannon 1 Quote
