Nerd...geometrically speaking, wouldn't the sending / receiving device that is to take advantage of a reflecting layer need to be some distance below the layer itself? Otherwise if it is at the same altitude, there would be no advantage to be derived from the "skip" that such a layer is able to provide. Actually on that basis the greatest advantage is to be derived from being located at ground level, as with most transmitters and receivers.
