What is RG214 Coax Cable?

The RG214 coax cable is a favored type of coax 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. The jacket allows for resistance against several environmental factors including abrasion and moisture. Additionally, the cable’s shielding prevents electrical interference giving the cable an excellent and consistent current. RG214 coax cable's Mil-Spec equivalent is M17/75-RG214. This coax 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.
