Ok, I see I need to clarify that statement.  I was not disputing the fact
that an RF transmission could not be extended to cover greater distances by
using a yagi, beam or parabolic antenna I know this and yes I also read that
section on point-to-point power limits.

The situation I was thinking of was of a wireless router or access point
with an out of the box physical configuration using the two supplied
omni-directionals (that most wireless routers come with) being mounted say
in the center of the 1st or 2nd floor of an office complex in a metropolitan
area.  Is it realistically possible to pick up a signal from 7 miles away
without any modification whatsoever to the transmitting station?

If so what type of setup would be required on the receiving end?

Sorry about the extended discussion on RF broadcasts, the main point

to point out was detecting a 802.11 2.4 GHz transmission from 7 miles away
would be almost impossible.

would indicate otherwise.
