phigan: N connectors have been around for decades.  Very common on RF 
systems, and have been for...... decades.

As a retired US Navy electronics technician, I can tell you that N 
connectors are not the collar/push/pull type that you are referring to.  
There are connectors of that type, but the N-type is a screw-on 
(threaded) connector of medium size, very common on Navy (and other) RF 
radio systems.

The N-type connector is not a push/pull, it is threaded.  There are 
indeed various push/pull types, but I don't recall them being common in 
RF systems.  One type that I know of is called "Lemo" and there are 
others, but generally not common in RF connections, I believe.
