I've had no problems after I put a o-ring around the center pin and pushed it up inside the plug. Then I screwed the plug onto the jack. It gets snug when the o-ring touches the jack. Another half turn compresses the o-ring and the connector has to be removed with a pair of slip-joint pliers (not the Channel-Lock type, the so called "gas" pliers). I learned this trick from a CB repair guy at a truck stop in the late 70s... He used it on every PL259 he put in a mobile installation. I was having lunch in the truck stop coffee shop and he walks in and spots my HT200 chattering away on the local ARES 2m repeater. We compared notes for about an hour then he invited me to see his shop... an old school bus that was front-half shop and rear-half motor home. He was a ham too - he had a Heathkit SB-301/401 over the bench, along with a couple of Regency scanners and an Icom 2m radio. The HF stuff talked to a choice of a long wire to the building, a Hustler mobile, or a school-bus length Connecticut Longhorn. The roof also sported 2m, 6m and UHF Larsens along with several CB antennas. Mike WA6ILQ
