NK 7/8″ feeder cable is a coaxial cable and its impedance is 50 ohms and also Its outer conductor made from corrugated copper and also its inner conductor is a copper tube. The feeder cables have been designed to meet the highest quality and environmental standards. These are produced in Finland, China and Brazil. Feeder cable mainly used for the connection of transmitter, receiver and antenna.
Application:
- Main feed line
- Riser-rated In-Building (JFN types)
- High quality and excellent performances
- Low attenuation
- High Power Rating
- Complete Shielding for minimizing system interference
