Question

how can i make a tv antanna for a hdtv using a coxia cable {the cable for Cable]

Answer 1

Coat hangers make much better antennas (you don't need anything special, just regular VHF and UHF antennas like before). Search for "coat hanger tv antenna" for some instructional web sites and videos.

A coaxial cable is designed to deliver the signal to and from an antenna, It doesn't make a good antenna on its own because of the metal layer under the insulation, which keeps interference away from the center wire when properly grounded.
