Just doing some more reading.. I'm confused why you said the Winegard HD7696P is no longer available, I see it for sale in a number of places still -

But using my CM4228.. any recommendations on direction to point in order to get CTV Kitchener and Toronto stations at the same time or if it's even possible?
