1/2″ SCF feeder cable is a coaxial cable with high flexibility and its outer conductor made from Helically corrugated copper and also its inner conductor is a copper clad aluminum wire. The feeder cable mainly used for the connection of transmitter, receiver and antenna and have wide applications in antenna feeder systems and also connection between wireless communication equipment or other low loss and VSWR signal transmission at high frequency.
Applications :
- OEM jumpers
- Main feed transitions to equipment
- GPS lines
- High quality and excellent performances
- Low attenuation and VSWR
- Complete Shielding for minimizing system interference
- Small coefficient of temperature
- Effective moisture-proofing
- High Power Rating
