Low VSWR Foam Dielectric RF Feeder Cable 50 Ohm 0.884Kg / M For Railway
Product Description
50ohms corrugated coaxial cables series have wide applications in antenna feeder systems as follows: Land mobile and cellular radio; Earth station antenna jumper cables; Jumpers for equipment room and antenna connection; Military data links; VLF, AM and FM radio broadcast systems; Point-to-point terrestrial microwave; Airborne and shipboard radar systems; Tactical, restoration and portable communication systems and others.
80% Super-high degree foaming polyethylene insulation features with low attenuation and stability in case of temperature variation due to small coefficient of temperature.
The insulation of longitudinally homogenous structure and extra-precisely corrugated copper tube outer conductor characteristic of low VSWR makes the cable your choice even in high-frequency applications.
