What is RG21 Coax Cable?

RG21 coax cable consists of high resistance wire with two silver-covered copper shields. As specified by the military’s MIL-C-17 guidelines for coax cable, RG21 coax cable also features a Type II non-contaminating PVC jacket. This cable is resistant to attenuation, abrasion, moisture, and electrical interference. It is rated for direct burial use, a maximum voltage of 2,700 volts, and temperatures ranging from -40°C to 80°C. RG21 coax cable is commonly used for communications applications. It can transmit various types of data including radio frequencies and video signals.
