5/4″ (1-1/4″) Feeder Cable is a coaxial cable and its impedance is 50 ohms and also its outer conductor made from ring corrugated copper and also its inner conductor is a smooth copper tube. corrugated copper tube coaxial cable is 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. Corrugated copper conductor is light, flexible and easily-bending thin-wallness therefore the coaxial 5/4 feeder cable is convenience for terminal work. This cable is RoHS compliant.
Applications:
- For the connection of transmitter, receiver and antenna
- Antenna feeder systems :
- Land mobile and cellular radio;
- Earth station antenna jumper cables
- Jumpers for equipments room
- Connection between wireless communication equipment
- And others
- High quality and excellent performances
- Low attenuation and VSWR
- Small coefficient of temperature
- Strong corrosion-resistant
- High power capacity
- Compliant with RoHS
