50 ohm 7/8" Radio Frequency Communication Feeder Cable for Antenns Feeder System
Applications:
50 ohms corrugated copper tube series coaxial cables have wide applications in antenna feeder systems as follows:
1. Land mobile and cellular radio,
2. Earth station antenna jumper cables,
3. Jumpers for equipments room and antenna connection,
4. Military data links,
5. VLF, AM and FM radio broadcast systems,
6. Point to point terrestrial microwave,
7. Airborne and shipboard radar systems,
8. Tactical, restoration and portable communication systems
9. Others.

Advantages:
1. Excellent Electrical performances: 80% super-high degree foaming polyethylene insulation of features with low attenuation and stability in case of temperature variation due to small coefficient of temperature. The insulation of longitudinally homogeneous structure and extra-precisely corrugated copper tube outer conductor characteristic of low VSWR makes the cable your choice even in high-frequency applications.
2. Simple use and complete range: The light, flexible and easily-bending thin-wall corrugated copper conductor offers convenience for terminal work. With totally 6 types in terms of dimensions, Hansen can provide the customer with exceptionally super-flexible kind(say 1/2? S) per their requirements.
3. Ease of maintenance: 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.
