What is RG179?

The RG179 Coax Cable is 75 ohm coaxial cable used in a variety of applications including security systems where high temperature is required. With a temperature maximum of 200°C, RG 179 cable also features a small, flexible diameter and a TFE taped outer jacket because of the high-temperature rating. Click on the links below to learn more about the different features of RG-179 cable.
