Ever try soldering a connector on to a cable on top of a tower on a windy day?
As for soldering skills, I have them, along with several different types/sizes of irons depending on what I'm doing. Even a 200 watt iron is going to have a hard time soldering a large connector on a windy day.
Yes, and the wind blew out my soldering iron......
Soldering skills: 1960's remember one test at a Motorola Service Station, they handed you a PL259 connector, a piece of coax, some rosin core solder, and a soldering iron. Then asked you to install the connector on the cable. The CORRECT answer was the soldering iron is too small, not enough heat capability.
Same thing applies today, Correct Tools................
