Absolutely not.  As I mentioned before even if you tower mounted an external
high-db omni outside (100 times the transmitting power of the little
built-in omnis) you could not get near 7 miles.  My estimation is that
considering the walls in the building, you would be doing good to pick up
anything 100 yards from the building edge, even with a yagi.
