Copper Tube Black PE Super Flexible Coax Cable 50 Ohm For Cellular Radio
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.
The special structure of high-degree physical foaming PE insulation and Corrugated copper tube outer conductor presents premises for effective moisture-proofing even without injection of drying-gases, thus assuring performances stability in terms of long period.
Application
1. CATV-community antenna television
2. CCTV-closed-circuit television
3. DBS-direct broadcasting satellite
