Plenty of mass in your heat source. One person already suggested a large iron. I use a 300+ watt gun. I also make sure that the coax is very relaxed and in a natural position, so that when it gets hot, there is less tendency for the conductors to migrate. I apply enough heat to get the solder to flow freely between the insert and the connector, flowing into the braid, but I don't hold the heat there long. I insist on having good flow on at least three of the four holes. As soon as it is soldered, I cool it rapidly with pliers as a heat sink. The entire time, the connector is held in a Panavice. After cooling the outer some, I solder the center, with the tip pointing down so as to not encourage migration further than necessary up the center. I then cool the center with a heat sink as well. Do NOT allow a blob of solder to form at the tip and trim any spike left over from soldering. A blob of solder will ruin the SO-239 socket, should there be one. It takes practice. I ruin about 5% of the connectors I install, but I'm leaning toward 70 these days. :o) If you mess one up, cut if off and do it again.
