I would advise you <against> placing the antenna inside the building behind the window. Not only may the RF wave suffer distortion, but more importantly, RF energy can be radiated back into the room. Remember: your AP operates at microwave frequencies. You must keep your exposure to microwaves to a minimum. To be certain that you will have adequate throughput, you must have adequate signal strength at both sites. At 2400 Mhz (802.11b), line of sight is ideal and path loss would be your only obstacle. Buildings are opaque at microwave frequencies.
