Dish tailgater to all 4 TVs

I think they mean it will not work thru the antenna amp/ switch box and associated wiring. Mine worked thru the Monte wiring if I disconnected the short jumper on the dual coax connector wall plate and connected the receiver to that. That effectively connected the Tailgater directly to the receiver but thru a short length of the Monte's internal wiring.
I later added a new coax input specifically for the sat receiver.
