I have a "one off" temp install....I am modulating four Direct TV chanels over coax....I need to make a 1200-1400 ft run.....sure, I know....LONG! Can I use RG-11, a couple of 35Db amps in line and end up with a useable signal on the four channels on the end of the run? End will get split over 4 displays. I have read you can "conceivably" run RG-11 up to 1000 meters....That seems far fetched. HELP!!!
