What is RG214?

The RG214 cable is a favored type of coaxial cable used for high-frequency signal transmissions. It is constructed with a stranded, silver-plated inner conductor, polyethylene dielectric, two silver-plated copper outer conductors and a PVC jacket. RG214's Mil-Spec equivalent is M17/75-RG214.

RG 214 Coax Cable Uses & Applications:

This coaxial cable is used in telecommunications, data transmission, radio frequency communication, broadcast, and computer applications. It is used to connect wireless and data communication systems that require high signal sequences and low attenuation, as well as in test leads and quality installations requiring low PIM and cross talk. The RG214 coax cable is also popular with radio frequency and microwave transmission in LAN networks and instrumentation or control applications.
