In this picture the crimp has been executed. You want to make sure to crimp in the middle of the crimp band. Doing this leaves smooth strain relief and no hard edges to impinge on the jacket.
For the soldering I use a mini-butane torch. A true Ham radio guy might cringe but when working out side, at a mast rack, in a boat yard, or 40' in the air in a bosuns chair, a soldering iron just won't always cut it, especially with 15 knot winds.
I have done more bosuns chair soldering than I would ever like to. It is darn near impossible in the wind and being 40-60' in the air swinging around wildly, as Sea Ray's blast through "no wake" zone, makes it even harder....
