The cable consists of a solid inner conductor composed of silver-plated copper wire, which is then surrounded by a polyethylene dielectric tube.
Furthermore, this cable type is approved for direct burial. RG-223 cable is a type of high-frequency coaxial cable which offers improved shielding and lower signal loss compared to similar cables. RG-223/U Coax Cbl, Double-Shielded, 0. As such, it is ideal for many military & civil radio frequency (RF) operations including telecommunications, network (LAN/WAN) connections, GPS, test equipment, and ham/CB/other radio setups, as well as any other signal transfer applications in fields such as aerospace, scientific, and medical.
