What is RG 142?
RG 142 cable high temperature coax cable is used in interconnections between telecommunications equipment and is widely used for commercial wireless applications. It also works very well in sensitive environments with minimal space such as avionic bays. Specific applications of RG142 cable include radar, GPS and medical systems. Because it is approved for direct burial, RG 142 coax can be implemented in sophisticated underground connections while still holding a good shielding effectiveness.

Use in the military
The RG142 coax cable was specifically built for the United States Military in the World War II era. It has a military equivalent part number of M17/60-RG142. This part number gives the United States Military an excellent option to use the highly reliable coaxial cable in their satellites, systems, and other tactical operations and equipment. Because of the obvious importance in these cables, the military requires them to have minimum and maximum dielectric adhesion values, specific shrinkback allowance, eccentricity standardizations, stress crack resistance tests, and many more specifications that add to the durability and reliability of the RG142. All trusted manufacturers will produce the same high quality cable because of its high QPL, which demands stability and rigidity in the testing and construction of specs and authenticity.
Benefits of the RG 142 Coaxial Cables
RG142 meets all MIL-C-17 specifications and utilizes standard connectors, so proprietary or exotic pieces are not required to build its infrastructure. This coaxial cable also has good shielding effectiveness (between 40 and 60 db) and has Low Passive Intermod (PIM) degradation of signal quality which is kept to a minimum. Since the RG142 is made with a solid dielectric this allows a high rate of crush resistance, which makes it the coax of choice for tactical operations and applications. Even though the RG 142 isn't your most phase stable wire, the phase stability can be enhanced through preconditioning in the specific temperature ranges of your project.
RG 142 Loss Attenuation Specifications by Frequency
||Attenuation (db per 100 feet)
The RG 142 loss is widely accepted at HF frequencies. Because it is constructed with a silver plated outer conductor this prevents oxidation of the conductor which decreases loss vs time.
Power Handling by Frequency
The RG142 has first-rate power handling capabilities due to the solid dielectric materials.
