Been there, and frankly it sucks when you don't get instructions. Trouble is I use 50 ohm and RG58 so not exactly the same. The 50 ohm type always have an insulator that surrounds the pin and extends to the front. In clamp type connectors it's usually loose but in crimp ones it's captive. By elimination the only place I can see it going is between the trimmed end of the coax and the pin but even that I'm not convinced of. Since you imply it's a small quantity if you have a choice I would advise using the clamp type that comes with a longish sealing gasket, cylindrical about 5mm or 1/5 inch long. Don't know the make. There's another type with a different clamp and a very thin gasket but we won't use them. I guess it's a foregone conclusion you're stuck with crimp type? Can you get anything out of the supplier?
