RG143 Coax Cable

What is RG143 Coax Cable?

RG143 coax cable is approved for military use by MIL-C-17 and is equivalent to M17/112-RG304 coax cable. Made from a silver-covered copper clad steel conductor, this cable is rated for up to 3,000 volts. This conductor is able to carry a consistent and strong current without worry of interference due to its two silver-covered copper shields. As specified by MIL-C-17, RG143 coax cable is jacketed with impregnated Type V fiberglass that allows for increased flexibility and protection against abrasion and high heat. RG143 coax cable is safe to use in applications that require direct burial or resistance to temperatures ranging from -55°C to 250°C.
