Product details

75 Ohm HD BNC for Video and Broadband

It terminates to RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179 cable groups — a common fit for HD-SDI, CCTV, and broadcast video infrastructure. The connector uses a solder contact termination with a crimp shield, giving a reliable electrical and mechanical bond to the cable braid and centre conductor. Rated to 3 GHz, this connector covers the full bandwidth of 3G-SDI and most broadband video signals without significant roll-off.

Impedance: 75 Ohm, Not 50 Ohm

This connector is built for 75 Ohm systems. The impedance is set by the dielectric geometry and the PTFE insulator.

The connector accepts RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179 cables — all 75 Ohm miniature coax types with a nominal 0.100-inch jacket diameter.
