[MLB-WIRELESS] Hills Reflector focal point

[Liam Devanny]

A bit of a hack way is to get aluminum foil and put it on the inside of 
the dish with the shinny side out. Then put a strong light source in 
front of the dish (the sun or another source), the point where the 
light converges into a point is the focal point. This is pretty rough, 
but the only other way I can think of is using geometry but then you 
need to model the dishes curve.
