Tejat’s British F-type male and female adapter cable (F-JJ) is specially designed for RF signal transmission. It uses high-precision 50Ω impedance matching RG142/RG58 coaxial cable, supports DC-3GHz broadband signal transmission, and has an insertion loss as low as 0.2dB@2GHz and a standing wave ratio of ≤1.3, ensuring the signal integrity of broadcast television, cellular base stations and security monitoring systems. Both the male and female connectors conform to the British F-type interface standard (thread outer diameter 9.5mm), are compatible with mainstream communication equipment such as Huawei and Ericsson, and support fast cable docking and flexible expansion.
