Surelink CATV black trunk cable RG6 Communication Coaxcial Catv Cable
Description
Coaxial cable is an electrical cable consisting of a centre conductor wire, coated by PE or Foamed PE insulation,
surrounded by cylindric conducting sheath, usually surrounded by a final insulating layer. It is used as a high-
frequency transmission line to carry a high-frequency or broadband signal. As to lansan,mainly supplying the
most common coaxial cable in use including RG8,RG58 of 50ohm impedance, RG6 ,RG11, RG59 of 75ohm
impedance.
Application
50 ohm coaxes, used in radio transmission and computer networks, RG-8 being a rather large cable.
