Ours was done free by direct tv.
No, I beg to differ. RG59 was pretty much always used as the standard size for cable hookups for decades, and electrically it's indifferent to RG6 or even RG11. The largest difference is the shielding present in each type. RG6 is a larger diameter due to higher shielding. The differences between the these two would only become apparent as you cross over 500' or so. I don't think there is over 500' in any of our motor homes. There are countless 10's of thousands of satellite DirecTV and DiSH installations using the homeowners original CATV with no problems. Especially since the original poster is using a non-HD, non SWM DirecTV signal... I know for a fact that works fine on RG58 50 ohm up to about 100 feet! hehe
IF you had a problem in your Motorhome and replacing the cable fixed it then you most likely had a pre-existing problem of corroded terminal ends, the dreaded black wire disease or perhaps a faulty connection elsewhere. I can almost assure that your signal problems were not due to the your existing wiring being of a 'cable' grade.
