What is "U-shaped area in the connector body"? I see replies with guys using 200-300W irons! Not seen that high of wattage with tip small enough to fit into slot of body with holes in it? My 100 watt (1/4" tapered flat tip) iron seems to work well there. We had a demo at ham club meeting a couple of years ago. Guy brought a micro-ohm meter (Kelvin bridge) and compared resistance of soldered vs. crimped UHF connectors. He used 100W iron like mine. Guess which type had the lower resistance? 73, Mike

Here's suggestions ... Use --only-- silver-plated connectors with silver-plated shells. Tin the braid and then treat it as if it was a piece of tubing and cut it to length with a small tubing cutter. Leave about a 1/16" portion of the center dielectric protruding from the braid when the dielectric is removed from the center conductor. There's a recess in the center pin's insulation to accept this protrusion. Use a taper reamer to enlarge the four solder holes in the body of the connector as much as possible. The holes will then be the diameter of the U-shaped area in the connector body, making soldering iron contact with the previously tinned braid much easier. This is a good place to remember to put the shell of the connector on the coax ... in the correct direction. (;-) The threads inside the connector are for screwing the connector onto the outer jacket of the cable and ---not--- for screwing reducers for RG-58 or RG-59 into the connector. That's an incidental came- later feature. Note that the threads inside the connector are "square" to prevent cutting into the outer jacket of the cable. Hint: A tiny touch of silicone grease on the outside of the jacket will help ... the ribbed front portion of the connector is for finger gripping ... or perhaps a small assist with slip-joint pliers. There is a correct way to handle RG-58 and RG-59 reducers and solder them correctly. 73!
