If you use Bell TV in Canada and are switching to HDTV, and you plan on using 3 or more HDTV receivers, then this is the product you need. You will also require a DPP Twin LNB and DPP Separators.
Bell TV carries the DPP Twin LNB and Separators, but not the DPP44 switch. If you have three or four HDTV receivers, Bell must install a second dish on your house. If you order this DPP44 switch, you only need ONE DISH to service four HDTV receivers. I have this system working in my house and my In-Law's house. AND, very important, if you are using dual-tuner receivers, you will NOT require additional satellite cables installed, which is a huge bonus. Bell TV should have been using the DPP44 switch a long time ago.
