I continue to be mystified by the fact that the amateur radio
community insists on using PL259 connectors. N-type are much more
reliable (used by professional communicators), low cost, can be crimped
easily and quickly and have a well-defined impedance right up into GHz
frequencies. 

Back in 2005 I started having contact problems with the
connector on my SteppIR 3-element. There was a thin layer of oxide that
built up around the centre pin of the PL259. I had had similar problems
with other connectors around my shack. I decided to change my entire
station, including the SteppIR, to N-type, and have never looked back.

soldering PL-259s.

The connector body is silver and the shell is nickel and you can buy
them from Mouser or DX Engineering.
