Tv antenna rotators are Not channel surfing friendly , must wait for antenna to rotate and not every one in the house will agree on the direction the antenna is aimed.

For your reception situation I recommend install the HD7084P antenna system for reception of Chicago Tv stations.
As a test to see if you will like to receive the Milwaukee Stations , by hand , aim the HD7084P antenna at about 17 degree magnetic compass direction.
If you choose to receive the Milwaukee stations install a second HD7084P antenna system that is set up the same as the antenna system for the Chicago Tv stations.
The Chicago and Milwaukee Tv antennas systems will be Separate antenna systems all the way to the locations of the Tv's and Will Not be connected together on to one coax.
The Separate antenna systems will be connected to a Remote control A/B antenna coax switch at each Tv location.
