Answer 2

Ok, very confusing subject hope not to confuse you more. There is an HD cable but it is not called an hd coax cable (no such thing). It would be called an HDMI cable. They are pretty expensive when you buy one, don't go cheap. The cheaper the cord, the cheaper the quality, and that's no good. Before you buy a cord make sure you have a cable or satellite box that is high definition as well as a tv that is high definition. Both should have a HDMI hook up (it looks like something you plug into the back of your computer). If you do have both, then all you need to do is connect your HDMI cable from your box to your t.v. Disconnect all other cables and then change your t.v. input to HDMI. I hope this is helpful to you, I don't explain stuff very well so good luck.
HIGH DEFINITION CABLE IS SO MUCH BETTER THAN REGULAR.

Answer 3

Coaxial cable is a shielded cable with a single copper wire, called the conductive core.

Other popular cable using copper has 8 wires (4 pairs of wires) and is typically not shielded.
