[UK-CONTEST] PL259 Plugs

[Fred Handscombe]

I think "better" is only a relative term when talking about PL259s!!

All my outdoor connections are N type, thats what I call better!

A guy I worked for (sadly now deceased) and not ever a ham but a keen RF 
engineer, used to do a demo for the radio clubs showing the effects of 
various connectors using a sweeper.  PL259s are not 50 ohms and have a 
really bad mismatch when coupled with a back to back or plug/socket.

N types dont

YMMV
