A feeder is a transmission channel for electromagnetic waves, whose function is to transmit high-frequency energy. The feeder cable can effectively transmit the signal received by the antenna, with small distortion, low loss, strong anti-interference capability, and a good impedance match between the feed line and the antenna, and between the signal input of the receiver. In large projects, Coaxial cable is an essential cable, simple connection, and low failure rate after installation. Accept customization of OEM or ODM.
