I've found that wiggling the body of the plug while tightening the threads makes the pl259 quite tight with the pins firmly seated in the notches. The motion allows the pins to find the deepest well of the notch.

This is simply not true. The entire PL259 body and shell and the entire mating body are part of the connection. What IS correct is that 1) the connectors must be properly installed both to the coax and the equipment, and 2) that the shell must be well tightened, often described as "wrench tight," with the pins on the PL259 firmly seated in the notches in the mating connector. I'm being generic about mating connectors because it's equally true of SO239 and other connectors like barrels, elbows, tees, and inter-series adapters. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
