BNC IS DESIGNED FOR A 75 O CABLE, NOT THE 50 O CHARACTERISTIC IMPEDANCE OF
RG 8X?  ALSO, THE LARGER CENTER PIN IN THE 50 O CONNECTOR CAN DEFORM THE
CENTER CONTACT IN THE MATING, 75 O FEMALE CONNECTOR AND MAKE AN UNRELIABLE
CONNECTION IF THAT FEMALE CONNECTOR IS EVER USED WITH A 75 O BNC CONNECTOR.
A AMPHENOL OFFERS 50 O BNC PLUGS IN RG 59 SIZE, AND THOSE ARE THE MOST
COMMONLY AVAILABLE ONES.  YES, THERE ARE 75 O BNCS AVAILABLE, BUT YOU HAVE
TO LOOK FOR THEM AND, UNLIKE THE LARGER TYPE N CONNECTORS, THEY DO NOT HAVE
DIFFERENT SIZED PINS THAN THE 50 O PLUGS.  THE FOLLOWING IS FROM THE
AMPHENOL WEB PAGE.  AMPHENOL ALSO OFFERS A FULL LINE OF 75 O BNC CONNECTORS
TO MEET THE NEEDS FOR HIGHER PERFORMANCE IMPEDANCE MATCHED CABLE
