The best way to tweak the mic position is to listen. Set up a speaker
outdoors playing broad-band noise (hiss) from a radio tuned
off-channel. Go forty feet out with your dish and listen with
headphones. Take care to aim the dish precisely by listening. Then
slide the mic in and out. You'll hear the focal point! Put a piece of
tape or make a permanent mark on the mic.
