►Antenna Feeder Cable
Antenna car antenna receivers transmit analog signals to car stereos, feeder has the characteristics of high resistance to interference and low attenuation, the main three types, low frequency AM FM, high frequency GPS/GSM/CMMB/DVB, connector harness according to the customer's design requirements and add protection tube, tape and additional components such as tie, in full compliance with the standards for vehicles and depots criteria.
．connection antenna accept device of signal transmission to car audio.
．has high anti-interference and the low attenuation of characteristics meter.
．three types, low frequency AM FM, high frequency GPS/GSM/CMMB/DVB.
．can according to customers’ needs to select specific of connection device and the wire, and in accordance with body of design increased protection tube tape and the tied with, parts, fixed and the protection line beam avoid injury.
．it meets car rules grade of tolerance and electrical performance
