Hi Guys, I currently have a 7100, 508 and 921 all hooked up to a sw64 and receiving signals from Dish 500 and 61.5. As you can see all my available lines are used up and I have never had a switch problem. I'm getting a 942 next week and would like your input as to what additional switch would be needed (sw44)? This will be a lease so an installer will be coming...is the additional switch included on the lease? Thanks for the help.
