I am planning to build one of these, however being somewhat new to antenna theory, is the orientation of the antenna critical? For example will it make a difference to mount it vertically or horizontally.
Yes it is very critical , so critical that Satellite Operators use this principle to reuse the same bandwith or set of frecuencies on the Satellite. It is called polarization of the signal , in OTA TV signals either VHF or UHF they use horizontal polarization, it means that the Transmitting Antenna is oriented horizontally therefore you should locate your antenna the same way , horizontally.
