RG142 Coax Cable

What is RG142 Coax Cable?

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

RG142 coaxial cable, also known as RG-C, is an ideal choice for any small room. RG142 is a flexible coaxial cable, which means that it is resistant to static build-up and high levels of electromagnetic interference. It is also incredibly durable, as it has been designed with a specific, patented, thermo-electric dielectric. This dielectric can withstand temperatures up to 200 degrees Celsius. The top-quality material used in the construction of RG142 coaxial cable makes it a great choice. However, in order to get the best from RG142 coaxial cable, you need to ensure that you are using the best quality connectors, shielding and core structures available.

RG142 coaxial cable is strong but still flexible. This means that it can bend into almost any shape. RG142 coaxial cable can also be used as a monitor cable, video cable, or even a digital voice cable, although it is important to remember that the additional shielding will make these cables more efficient. In order to use your RG142 as a line splitter, place the two cables which are together to create a second-order splitter. This makes it possible to run a signal between two computers or devices. Even though the RF signal is lost, the signal is not interrupted; instead, it is re-routed through the RF amplifier.

Benefits of the RG-142 Coax Cable

RG142 meets all MIL-C-17 specifications and utilizes standard connectors, so proprietary or exotic pieces are not required to build its infrastructure. RG142 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 RG142 isn't your most phase stable wire, the phase stability can be enhanced through preconditioning in the specific temperature ranges of your project. A similar coax cable to RG142 is the RG400. The RG400 coax cable is well-suited for projects requiring the operations of satellites systems, tactical operations, and equipment. You can learn more about these two formidable coax cables side by side in here.

Use in the military

The RG142 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 RG142 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 shrink back 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 RG142 because of its high QPL, which demands stability and rigidity in the testing and construction of specs and authenticity.                                                 Back to the top

RG142 Cable Loss Attenuation Specifications by Frequency

The RG142 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.
