Re: [Elecraft] Reliable PL-259 UHF connector engagement

I would suggest NOT using metal tools to tighten/loosen PL-259 connectors. Too much of an opportunity to damage the connector. The silicon "mat", for want of a better term, used to loosen jar lids is the way to go. Cut a piece ~3"L X 1"W and you have a good method to "get a grip" on the

Hi George, I was over program services in Dallas back in the 1970’s for Southwestern Bell. We provided the last mile for radio and TV remote operations. I spent more than a little time handing off our end. We also provided studio to transmitter links. I saw that tool in use at just about

Re: [Elecraft] Reliable PL-259 UHF connector engagement

As someone who is currently switching bands by going outside and replugging PL259s, I fully agree that other connectors, e.g. BNC would be nicer. I have gotten in the habit of skipping pulling out my LeatherMan and instead joining the connection to the point where I can feel the teeth

Andy, In the 60s & 70s, we had a screwdriver like tool for removing and inserting PL-259 connectors in patch-bays in TV stations. It was a screwdriver handle and shaft with a steel tube slightly smaller than the pl-259. The tube had a longitudinal slot that was big enough for the cable to

When I worked in the aerospace industry it was common practice to use special "pliers" for removing "Cannon" multi-pin round connectors. These were not any old plumber's pipe wrench (you know - the ones that plumbers use to destroy chrome finish bathroom fittings) but a special tool designed

[Elecraft] Reliable PL-259 UHF connector engagement

PL-259's are excellent connectors when installed and used correctly. Unlike N and BNC connectors, a PL-259 is dependent on proper engagement of its outer shell and interconnecting teeth to the mating SO-239 socket. Use a small pair of pliers to snug up -- not tighten -- the shell. Be
