[Elecraft] BNCs

[Sandy Blaize]

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!!
