What is RG213 Coaxial Cable?

The RG213 Coax Cable is 50 ohm coaxial cable used in a vast array of military and commercial applications. With a temperature maximum of 75°C, in line with other coax cables like the RG142 Cable, this allows installation in heat sensitive environments. RG 213 cable may be used in radio communications, high-performance electrical and data transmission, broadcast, and computer applications. RG-213 cable is also used as antenna feed cable when low signal loss and high operating voltage are required. VHF and UHF applications are also common uses for RG-213 coax cable.

What is the difference between M17/74-RG213 coax cable vs. RG-213 coaxial cable?

M17/74-RG213 is the Mil-Spec equivalent to the commercial grade RG-213 cable. M17/74-RG213 coax cable is used for high frequency signal transmission and has two key differences from the commercial grade coaxial cable. These differences include a maximum operating temperature of 85°C and a M17/189-0001 LS/LT Jacket.
