It is designed for the 75 Ohm video and broadcast signal chain, not the 50 Ohm RF test equipment standard. The bayonet coupling provides a quarter-turn positive lock that holds the cable pair mated without tools, standard for field-terminated video runs. Insertion loss is rated at 0.1 dB, a tight figure that matters on long cable runs where every tenth of a dB adds up.
Insertion loss is rated at 0.1 dB, a low figure that suits long video cable runs where loss budget is tight.
