Dex 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

Thanks, Dex Also if you have to use the uhf connector then winding a strip of rubber cable sealant over the coax and plug assures a tight water tight mechanically secure joint , your local electrical supply house should stock it , I prefer Nitto tape . _ Advertisement: Your Future Starts Here.

RE: [Repeater-Builder] Mini - UHF Connector
Don, I have to wonder: Who makes the mini-UHF connector that is the problem? My connector of choice is the RFU-600-6 crimp connector made by RF Industries. It's available through TESSCO and other commercial radio supply houses. This connector works on MaxTrac, Radius, GM300, M1225, R1225, and CDM radios, so I feel it also will work on GTX and Spectra radios. Don't worry about a puny 110 watt radio; the mini-UHF is specified up to 2.5 GHz and better than 2,000 watts. Well, that is the spec for the RF Industries connector, which is machined brass and has silver-plated contacts and a PTFE dielectric. Some of Amphenol's economy connectors have a phenolic insulator that may not perform as well. YMMV! 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Don Sent: Wednesday, April 18, 2007 2:39 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Mini - UHF Connector I have a Problem in Finding a GOOD Mini UHF Connector for The Motorola GTX And Spectra 900 Mhz . . The problem is No Matter how Tight with a Pair Pliers I get them they still are loose, While taking another look on the ones I got NO Matter how tight the Outer ring it will NOT Make a difference Because it is Hitting the Back of the connector on the Radio Before it Tightens up And the other Part is Loose. , I Took a Dremel and Cut off Part of the Back of the adapter, that Works Great. But I need to Know what everyone else is using, Maybe Amphenol and Part Number. Also I got a Motorola Spectra VHF-UHF 110 Watts Coming soon, . I cannot believe they use a Mini UHF On the radios at that Power. Thanks Don KA9QJG

RE: [Repeater-Builder] Mini - UHF Connector
All, Over the years I have observed many destroyed Mini-UHF jacks. Most failures were caused by using a Mini-UHF to UHF or N adapter that are about ¾ to 1.5 inches long. These adapters place a tremendous amount of strain on the jack. Most of them will work themselves loose and start chewing the teeth off of the jacks. Mother M makes an adapter cable that has a Mini-UHF male with a short (6 inch) length of RG58U/A cable to a UHF female connector. This would allow a installation that could have the jumper tied up and supported in such a manner to relieve any strain on the jack. I have even used a male Mini-UHF male and a short run of cable to adapt large hard-line cables to a UHF link radio that had a antenna at the 300 ft level of a tower. Worked like a charm Respectfully WA9NE -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Vincent Caruso Sent: Wednesday, April 18, 2007 9:05 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Mini - UHF Connector Thats funny, I was just reading your original post and when you mentioned tightening with pliers I was about to reply asking if you were using the RS connectors.
