Now might be a good time for experienced dealers/technicians to post diagrams for whole house distribution systems I use a VIP612 with an output on SDch3 combined with a SC3 signal combiner. The SC3 combines OTA with ch3 so I can watch satellite or OTA in 7 rooms, without additional receivers fees. I have DVR on CH3 in all 7 rooms and HD only on the 55"TV at the 612. I do have OTA HD in all 7 rooms so that includes FOX, NBC,ABC & CBS. That is cheaper than DISH's hokey DVR fees and outrageous additional receiver fees.
