[R-390] (no subject)

[Gary I. Biasini]

Folks, 

Following on Larry's message, I have now learned that the mini-BNC
connectors used in the R-390a are "reverse polarity" mini-BNC connectors.
While I was able to find many reverse polarity BNC connectors on the web, no
luck finding the mini-BNC variety.

As my former classmate, Shaun Merrigan, mentioned, they are available at
Fair Radio for $4 each, at least when I checked last night.

Gary

Larry,

 

Thanks.  I was surprised how easy it was to find after others have had no
luck.  I appreciate your attention to detail.  

 

Have a great weekend.

 

Gary

Hi Gary,  Sorry to disappoint, but the connectors you are referring to have
a male pin as the connector for the center conductor.  The ones used in the
R-390A have a female connector for the center wire.

 

Regards, Larry

Greetings and good evening
Looking for part number of the mini BNC connectors inside the R390A. I am
rebuilding one completely and want to replace all of the coax between
modules. I have coax and want to build new cables.
