I don't know the Kalamzoo area (except that Gibson made guitars there in the 60's, and now Heritage uses the facilities), but you need a good line-of-sight from your antenna to the HD transmiter antenna. Depending on antenna height and transmitter power, 30-40 miles is about the best you'll be able to do on distance. The HD transmitter is not always co-located with the main station transmitter.
Your local HD TV stations probably have web sites. Check these out and look for high def info. You can also call the engineer at each station descibing your location and asking for recommendations, or send him/her an email.
