For what it might be worth, I only use 7/16 DIN connectors for my jumpers and transmission lines. When I have coax switches and baluns made, as well as accessories such as power meters, I always order them with 7/16 DINs. I also always buy either Andrew or Times Microwave connectors depending whether I am using hard line or coax such as LMR600 or LMR900. It costs a bunch more, but the 7/16 DIN connectors can't be beat.

Without sounding my horn too loudly I have servered on IEEE connector committees and been paid big bucks to solve the production line problems. Counterfet connectors is too mild a term. There is some real crap out there and your eyeballs won't be able to detect it. Things like finish and and spring tention problems can not be seen. I recall one particular connector that was causing a 2db measured loss over a prefered Kings or Amphenol connector. The imported brand X connector was available in both 50 and 75 ohm versions, both of which were unmarked. When actually measured with a TDR they both measured 62 ohms. Folks, life is too short to mess with S T U F F like this. Do you really have to touch the wet paint or believe the sign. 73, Fred, AE6QL -----Original Message----- >From: Fred Jensen <[hidden email]> >Sent: Oct 13, 2014 12:49 PM >To: [hidden email] >Subject: Re: [Elecraft] BNCs > >On 10/13/2014 10:42 AM, Sandy Blaize wrote: > >> There is a lot of "crap" parts available at hamfests these days!
