Rg-6, Rg-59

Can someone tell me what the difference is between RG-6 and RG-59 cable? I have DTV and am in need of buying cable. Which is the best to buy?
Thank you !

Get the RG-6. The biggest difference is bandwidth. Most RG-6 will say something like "Swept tested to 2GHz" on the cable sheathing. Plus, the shielding is much better on RG-6, rejecting more interference and delivering a higher quality signal.

I have seen plenty of installations work with RG-59, but then others that would not work at all!!! Cheaper RG-59 will not always carry the higher frequency signals required for satellite operation. In some instances, it would half-way work. Some channels would come in, others would not.

Basically, the rule of in satellite is RG-6.

Bandwidth is a big factor, I agree. But current handling is another story. My brother in law bought a house a couple of years ago that was pre-wired supposedly. after a couple of months of sat usage, everything failed. The whole system was wired with RG-59, and almost all of it was scorched; it could not handle the DC voltage from the receiver to the antenna and almost caused a fire hazard. Had to completely rewire with RG-6C. Do the job once and use RG-6C.

Yes, forgot about that too! Most of the receivers are sending 12-18 volts DC back to the dish.

RG6 is the only cable that is recommended for HD.
