Take you rf calculator out an put in 50mw into a 2.2 dbi omni, then put 
a 26dbi dish 7 miles away with perfect line of sight. Okay, click the 
'calculate' button. Got any signal left?
If you don't have a good antenna and output signal on BOTH ends, you'll 
get nada. That was the point. That was the answer to the original 
question. All this stuff about 70 mile links is fine, but it's irrelevant.
Can it be done with a dish like this?

Ask the cia, they probably know.
