The 1931872 (Pomona model 2249-C-72) is a 72-inch cable assembly designed for reliable connections in test and measurement. It is constructed with RG58C/U coaxial cable, featuring a characteristic impedance of 50 ohms, a 20 AWG tinned copper center conductor, and a tinned copper braid shield. The impedance-matched BNC connectors have gold-plated center contacts for noise-free signals and a durable PVC molded strain relief. This assembly is ideal for most test and measurement applications, RF transmission systems, and Thinnet LAN applications.
