Subject: [TowerTalk] PL-259 Electrical Joint Compound
After 15 years, a pair of PL-259 connectors have seized on mating SO-239 jacks
used on an outdoor RF choke. Is there anything more suitable than Penatrox-A
which is Au/Cu rated? Ideally, I'd like to apply a synthetic + conductive
grease on the mating SO-239 threads.
Unrelated, but while investigating the coax connectors, the LMR400-Ultraflex
cable I installed about 15 years ago has started to decompose. At the time of
installation, I knew the Ultraflex version has a shorter life span but wasn't
expecting such severe decomposition. The jacket is crumbling due to its rubber
composition. This past weekend, I replaced it with gelled LMR400-DB for direct
burial, but it's installed above ground. Like the original LMR400, the DB
version has a rugged polyethylene (PE) jacket.
