Twin-lead is a balanced transmission line consisting of two parallel conductors separated by a flat plastic insulator, with a characteristic impedance of 300Ω. The cable connects to the television through a pair of spade-lug screw terminals on the rear panel, typically labeled with the band (UHF or VHF) and impedance. | Twin-lead is a balanced transmission line consisting of two parallel conductors separated by a flat plastic insulator, with a characteristic impedance of 300Ω.
