[R-390] Is this the same mini-BNC connector?

[Michael Murphy]

Tim,

The connector used in the R-390 is not a mini-BNC in my book. A proper BNC
has a pin! The Amphenol connector used in the R-390 has a socket instead of
a center pin thus making it a "Reverse mini -BNC". Ha!

Amphenol discontinued this connector series a few years ago. Only one
company still makes this connector (well sort of) It is RF Industries in
California. http://www.rfcoaxconnectors.com/

The one that they make is 75 Ohms and will work only with RG-59 coax -
unfortunately not mini-coax. They also make a bulkhead. These are compatible
but are fairly useless except for test cables.. It is cheap, only a few
dollars each, last time I bought some for work.

The new Mini-BNC as you have found is simply a small BNC design. The world
apparently needed one more connector. It is not compatible with the R-390.
Darn..

Is this the same as our favorite mini-BNC connector?
Seems to be making a comeback in the "wireless" world:

None of the prices are as cheap as Fair's!
