[time-nuts] BNC Question

[Brucekareen at aol.com]

Interestingly, 50 and 75-ohm BNC connectors have the same pin/shell  
dimensions and properly couple together.  For more information go to

(http://www.cliftonlaboratories.com/august_2007.htm)  and  scroll down to the 02 August 2007 entry.  There is a 
link to the Amphenol  site for specifics about the connectors.
 
I am planning to use an Extron video distribution amplifier for standard  
frequency distribution.  The 75-ohm connectors will be OK.  These  amplifiers 
feed multiple 75-ohm outputs from a "zero-impedance" source by  inserting a 
75-ohm resistor in each leg.  Some folks using these for  standard 
frequency distribution change the resistors to 50-ohms.
