Shari, Read also about Fresnel Zone if you plan to position the antenna in the middle of the building! You will have to clear the edges of the buiding (wikipedia has a great explanation and formulas to make an estimate of the height of your pole). Usually the way we do this kind of coverage is by installing multiple Window unit antennas from inside the building. We make sure that tinted windows are not blocking the signal, and when it works it prevents drilling the roof and having to deal with lightning safety. The Andrew brand used to have great Window Antennas...don't trust the suction cups too much, glue those!
