A Correct answer
Explanation

Coaxial cabling has a single copper conductor at its centre. A plastic layer provides insulation between the centre conductor and a braided metal shield. The metal shield helps to block any outside interference, therefore we use it in CABLE TV. Thin coaxial cable is known as thinnet (10base2). The most common ones are RG 59(Coaxial cable) and a low loss cable is RG 6, both are 72 ohm for TV sets and antennas.
