I am currently a Directv customer, but plan to switch to Dish. I have 2 tv's - one HD and one SD. I am hoping to get a 722 receiver. The distance between the two tv's will require approx 80-90 ft of coax. Right now I have RG59 and Dish has told me that they would replace it with RG6. My question is whether it will cause any reception problems with the tv's being 80-90 ft apart. If so, what is the recommended maximum distance between two tv's on a 722 receiver?
