You need a high sensitivity, less noisy card. Compex cards are often called as bad junks and not advised for such setups.

For mini-PCI cards best bet are :

SR2
SR5
DCMA-82

DCMA-82 topping out in the list with a peak output of 1W in b/g and 400mW in "a" mode.

The choice is yours

Noise level does not increase much with the higher gain omni on top of a building.
So, you do accept that noise level increases with the increase of gain.
