Google is bringing up a 3671 but I've not found a 3176.  Could that be a typo?

I really appreciate you posting that information.  I get 3 channels some of the time, 2 that carry cbs with only a difference in which towns they highlite local news out of.

I do not watch much tv but I know there are some good documentaries on some pbs stations.  I just said today that I need to get an antenna bought.  Is the best place to buy one on-line or are they available at other outlets?
