Figure 4-1. Coaxial Connector Examples

The types of coaxial cables used by Comtech EF Data are 'BNC', 'TNC', 'N', 'F',
and 'SMA'. Coaxial cables (plugs) and their mating connectors (jacks/sockets) are
available in two coupling styles – Bayonet or Threaded:
Bayonet Coupling Style – The jack has a pair of guideposts that accommodate
the plug's lockdown slots. This lockdown design provides secure assembly
without over-tightening the connection.
Threaded Coupling Style – The jack features external threads. The plug shell
features internal threads, and has either a knurled outer surface to permit hand-
tightening of the connection, or hex flats to accommodate torqued installation.
Connection Instructions:
Bayonet Coupling Connections – Use the plug slots to guide, and then slide the
plug onto the jack posts. Then, turn the plug clockwise until the jack posts are
fully seated within the plug slot.
Threaded Coupling Connections – Engage the plug onto the jack threads, and
then turn the plug clockwise until it is fully threaded onto the jack. Do not over-
tighten the connection.
