Fw: [Elecraft] 50 vs 75 ohm N-connectors

[Ken Kopp]

Jim's correct - There ARE differences between 75 and 50 ohm coax
connectors ... especially Type N.

Not so.  There is a very real physical difference between 50-ohm and 
75-ohm
type N connectors.  The 50-ohm male pins are bigger than the 75-ohm pins 
and
will damage a 75-ohm female connector.  Likewise if a 75-ohm male is 
mated
with a 50-ohm female there will not be good electrical contact.

The impedance is a characteristic of the coax cable, not the connector.
What does matter is what coax cable(s) the N connectors are designed 
for,
such as RG8, RG58, RG214, etc. Take a look at
http://www.smelectronics.us/typencableconnectors.htm. This might help 
you
match your connectors to their appropriate cables.
