The difference between RG59 and RG6 are the thickness of the center conductor which carries the signal, and also the shielding of that conductor. RG6, which is very similar to RG59, has a thicker center conductor for less signal loss on longer runs. RG6 has an aluminum braid and an aluminum shield, while RG59 comes with a copper braid.

RG6 has a little less signal loss, or attenuation, over 100 feet. RG6 has a better design for maintaining the signal levels inside the center conductor, especially over longer runs. This is the reason RG6 has become the standard for broadband CATV and satellite systems.

A basic rule of thumb is to use RG6 for any Rapid Frequencies, and use RG59 for video frequencies. For any broadband CATV or satellite system, RG6 is recommended by all the experts. For any signals that are video frequencies RG 59 will be adequate but RG6 could be used as well.
