Re: N connectors



 I've found that the 2 piece solder type of N connector last's longer then
the clamp type on my satellite antenna's preamp to antenna jumpers. The
constant moving causes the clamp type to fail at the shield wire clamp
junction.The 2 piece solder type last's quite a bit longer, I would say 4
times as long. I also have no problem soldering them....
