According to a couple tower locator sites the closest TV transmitters are located Northeast of Belleville about 25 miles away in the Detroit area. Only the FOX affiliate is broadcasting VHF on RF channel 7.
In the US, about 25% of TV stations are now broadcasting on the VHF band, mostly on VHF-Hi (ch 7 to 36). Only a handful are broadcasting on VHF-Lo (ch 2 to 6).
Multipath (ghosting in the analog days) can be a big problem for digital. This can be caused by signals being reflected off buildings, towers, trees or terrain. You need to point your antenna so it's receiving the strongest signal. One of your TVs may have a menu choice that displays signal strength. If not, the Winegard Sensar Pro is a combination signal strength meter and adjustable amplifier that will display signal level.
