50Ohm corrugated 7/8" Flexible Cable Feeder Cable Coaxial cable
Construction Characteristics:
High physically foaming insulation, copper tape formed, welded and corrugated to manufacture the outer conductor.
Advantages:
Low attenuation, low standing wave, high shielding, damp-proof gas free maintenance, flexible, high anti tensile strength.
Application Range:
Broadcast and television, microwave telecommunication, military use, aerospace, vessel or other circumstance where RF cable is needed.
Inner Conductor: Smooth Copper Tube/ Copper Coating Aluminum/ Helix Copper Tube
Dielectric : Physical Foaming Polyethelene(PE)
Outer Conductor: Corrugated Copper Tube/ Annularity Copper Tube/ Helix Copper Tube
Jacket : Black PE or Low Smoke Halogen-free Fire-retardant
