I assumed since I bought the dish and D/C-Feed all together and it came
with the mounting brackets I mentioned, that it was a complete system.
THus I was coonfused as to why the difference in mounting distance and
what K5OE said was the focal length.  I have now measured the 3'x2' dish
myself and I also compute a focal length of 15.5".  THus if I had just
blindly used the brackets that came with it, I would have been 3"  from
focal point.  Im glad I asked...
