Well, where shall I begin.
Problem 1 is WWMT-DT Ch 2 from Kalamazoo. Low VHF channels are prone to interference, thus pixellation and freezes on digital broadcasts. While they were interfering and forcing 8VSB down our throats, the FEDS should have made TV abandon channels 2-6 IMHO.
Problem 2 is you have a mixture of low VHF, high VHF and UHF stations, so you need either an all channel antenna (a compromise at best) or two antennas, one for VHF, one for UHF.
Problem 3 is the stations are three different directions, so you need a rotator for your antenna(s).
I , personally would go with a Channel Master 4228 for UHF, a Wade DWE 247(has good gain on Ch2 & 7)for VHF, connected with a Channel Master 7777 preamp (which has a built-in UHF/VHF joiner) and a Channel Master rotator.
UPN is not digital yet but you might look at

and input your latitude and longitude to see what is planned.
Also, your UPN stations are ALL class A (CA) or low power stations. They will be among the LAST to go digital.
