RG-142 is a high temperature coaxial cable used in interconnections between telecommunications equipment and is widely used for commercial wireless applications such as avionics, radar, GPS, and medical systems. Featuring a PTFE dielectric and FEP jacket the cable is rated for operation up to 200°C. The cable's 4.95 mm overall diameter makes it suitable for applications with limited space.
Shielding effectiveness of RG-142 is typically >80 dB to 6 GHz and >60 dB to its cutoff frequency of 12.4 GHz making it ideal for a range of microwave band applications.
