I've had excellent success with PL-259's. Prior to scewing on the
assembly, I LIGHTLY tin the braid and center conductor. This allows
the solder to flow very well. I've been using a Weller gun 100/140W
(now 30+ years old) with great success.
N connectors are another sotry. Maybe it's because I rarely use them,
but I always have trouble getting it to screw together. Seems that
rubber spacer is too wide. If anyone can tell me what the problem is
there, I'd appreciate it.
