RG & Mil-Spec

RG142 Cable & M17/60-RG142 Cable
50 ohm Rating
RG142 coaxial cable is constructed with a silver-coated copper clad steel conductor, PTFE dielectric, 2 silver-coated copper shields and a fiberglass jacket. It is typically used for interconnects or jumpers.

RG178B Cable & M17/93-RG178 Cable
50 ohm Rating
RG178 coax also has a silver-coated copper clad steel conductor and PTFE dielectric. It has a single silver-coated copper shield and a fluorinated ethylene propylene jacket.

RG179 Cable & M17/94-RG179 Cable
75 ohm Rating
RG179 coax also has a silver-coated copper clad steel conductor, PTFE dielectric, and a single silver-coated copper shield, but has a KEL-F jacket.

RG180 Cable & M17/095-RG180 Cable
95 ohm Rating
RG180 is constructed of the same materials as RG179, but because it is rated at 95 ohms it is used more for data transmission over cable TV and video like RG179.

RG188 Cable
50 ohm Rating
RG188 has both a PTFE jacket and insulation, with a silver-coated copper clad steel conductor and a single silver-coated copper shield.

RG214 Cable & M17/75-RG214 Cable
50 ohm Rating
RG214 has a non-contaminating PVC jacket and solid, low density polyethylene dielectric covering a silver-coated copper conductor and double shield. It is generally considered a low loss cable, and is often used to test leads.

RG223 Cable & M17/84-RG223 Cable
50 ohm Rating
Like RG214, RG223 has a silver-coated copper conductor and dual shield. It has a solid, low density polyethylene dielectric and PVC jacket.

RG316 Cable & M17/113-RG316 Cable
50 ohm Rating
RG316 is constructed with a silver-coated copper clad steel conductor and a single silver-coated copper shield. It has solid PTFE dielectric and a fluorinated ethylene propylene jacket.

RG400 Cable & M17/128-RG400 Cable
50 ohm Rating
RG400 has a silver-coated copper conductor and dual shield with solid PTFE dielectric and a fluorinated ethylene propylene jacket.
