Yes and it does!Liquid electrical tape is about the only thing that works and stays. I will be using it where the matching coax ts soldered in on the C3i antennas. I was really surprised to find the solder joints gone on the 144 and 440 antennas. Epoxy works, but it deteriorates over a few years where the outer layer of the liquid tape only dulls a bit, which I believe is due to dust settling or "stuff" in the rain. At-any-rate the liquid tape remains viable as long as I've had it up so far. (Not quite 12 years) (bottom photo on link) http://www.rogerhalstead.com/ham_files/tower.htm Click on photos for a larger view. Unfortunately I have no current photos as that is now near the top of the tower that I can no longer climb. I might give the 500mm telephoto lens a try. I'm going to add a common mode choke of 8 turns of RG-400 on 7 cores as it is an end fed quarter wave fed against the tower. I've been thinking about a number of coils in a box switched in at the feed point to add length, so I can switch the resonant point down. I believe that will be more efficient than just a tuner in the den, or shop. 73 es thanks.

Even with 3 coats of clear Krylon, the solder connections on my C3i antennas dissolve every few years. OTOH Why would any connector used out doors fail faster than inside. Doesn't everyone weather proof them? I either go the flooded heat shrink, self vulcanizing tape, or coax seal. I can't imagine any connector not protected outdoors. Regardless of type, mine look like new when I take them down, unless they were hit by lightning, Of course, they may have some glue, tape, or coax seal stuck to them, but they are well protected.. 73 Roger (K8RI) On 5/13/2016 Friday 2:40 PM, Paul Christensen wrote:"I use them outside as well as inside and have never had a problem."Near salt air? Here along the eastern coast, salt air affects crimped connectivity over time unless Coax Seal or a variant is used. Theproblemis never the center conductor, but with the braided portion of the crimp. When soldered, it's never an issue.
