Hi, I'm looking to switch to Dish Network and have a few questions about installation:
1. does the 722 require two separate coax runs for the dual tuners, or can the 722 use my existing single coax cable?
2. How does the second TV get it's signal? Do they have to run an additional coax out to TV2, or is a single cable capable of distributing the signal back out to through my existing wiring to my second SD TV?
3. If TV2 uses the existing coax, would I be able to access the TV2 signal on any TV connected to the home's coax from multiple rooms?
Obviously my concern is having to run extra cables, and I'd like to avoid that if at all possible. Ideally, I would like to use one receiver to have a primary HD feed and then be able to access the TV2 feed from 2-3 other TVs located throughout the house. I understand that my other SD TVs would only be able to watch the same program and I'd probably want to buy an additional RF remote in this scenario, but is that possible?
