Keying Options:

2-Lug - Utilize two lugs, set 180 degrees apart to provide an interface with the bayonet coupling sleeve.  BNC connectors are a popular series which utilize a two lug key.

4-Lug - Utilize four equally spaced lugs to provide an interface for the bayonet sleeve.

Threaded - Threaded coupling nuts are utilized in place of a bayonet coupling sleeve.  The TNC series is a popular example of a threaded connector.
