RG8 Coaxial 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.
