...your question is subjective. As you know, Chicagoland is huge (living there myself), so in that sense what works for one person might not work for another, even neighborhood to neighborhood, spare someone in Fox Lake vs Joliet . Solid objects/distance/topography/building structure/materials can affect reception. Bob's outdoor antenna is a better idea if you truly would like the best opportunity to maximize the amount/quality of ATSC signal to your TVs. Indoor antennas have a lot more issues IME.
