This is where having the complete azimuth receive pattern (or, at least, the peak gain, 3 dB bandwith, and front-to-back ratio) of the antenna and the TVFool report come in handy. One can "do the math" starting with the Noise Margins involved to see if "from the back" and "from a bit off-axis" can work. I won't recommend a fixed-position solution otherwise.
