coaxial cable Coaxial cable, or coax (pronounced ), is a type of electrical cable consisting of an inner Electrical conductor, conductor surrounded by a concentric conducting Electromagnetic shielding, shield, with the two separated by a dielectric (Insulat ...

used for domestic TV signals. It is one of the options of the Japanese cable standard JIS C 3501. * The 3 indicates approx diameter of the conductive core plus the dielectric (diameter of conductive core =0.5 mm, dielectric thickness =1.3 mm) * The C indicates a characteristic impedance of 75 ohms * The 2 indicates a solid PE dielectric core * The V indicates a single braided outer conductor (W would be double) Nominal loss at 100 MHz is 42 dB/km. With its narrow core it is similar to

RG-59 RG-59/U is a specific type of coaxial cable, often used for low-power video and Radio frequency, RF signal connections. The cable has a characteristic impedance of 75 Ohm (unit), ohms, and a capacitance of around 20pF/ft (60pF/m). The 75 oh ...

RG-6 RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, ''RG-6'', is generic and is applied to a wide variety of c ...

coax cable is better shielded and has lower losses.
