Not quite.If he's on the "wrong" side of his building in relation to the towers, it may tell him he can get the channels when in fact he can't. It does ask if there's "any buildings, steeples, towers, or other structures taller than four stories within four blocks of your location". The same building someone lives in could be the problem. In his case though, it sounds like he's generally facing the right direction.
I live on the southwest corner of the building. My balcony faces west. Most of my signals are coming from the southeast.
I tried moving my antenna from my living room (the balcony is off the living room) to the corner bedroom, which has a windows facing south and west. The south window gives me a straight shot southeast. Unfortunately, my signal for PBS, channel 25 (11.0 miles away, but has a notoriously weak signal), was about the same as it was in my living room. I suspect that whatever increase in signal strength I acheived from antenna placement was offset by having a 100 foot wire from the Terk TV20 to the HDTV.
