YES!!!! The 75 ohm series are UG-260/U connectors, the 50 ohm series is
the UG-88/U. If they don't have this stamped into the rear barrel of
the connector, THEY ARE Counterfeits or JUST PLAIN TRASH!
There is a lot of "crap" parts available at hamfests these days! Be
careful what you buy!!

Thanks Jim
I was going to ask that exact question. For the amateur world, does it
make a difference if a 75 ohm connector is installed on a 50 ohm feedline.
You made it very clear for everyone. Thanks!

Don't know where anyone got the idea that BNCs made for RG-8x we 75 ohm.
I worked in the tv industry for many years and we used hundreds of BNCs
that were made specifically for 75 ohm video. By the way, RG-59 not RG-79.
While you are entirely correct that there are 75 ohm and 50 ohm BNCs, the
difference DOES NOT MATTER at HF, because the connector is such a small
fraction of a wavelength and the difference is small. 75 ohm connectors
were important with analog video because of the smearing of very fine
detail in a high res image, and because studios do lots of patching and
routing.
