Yours is a simple reception situation and you will receive Many digital broadcast tv channels. Install a Antenna Craft Y5-2-6 VHF low band antenna for reception of WBRA-DT channel 3 PBS , aimed at about 360 degree magnetic compass. And install a Antenna Craft U4000 UHF antenna aimed at about 130 degree magnetic compass. Connect the two antennas together with a UVSJ UHF/VHF Seprator Joiner. That joines the two antennas on to one coax. the output of the UVSJ will connect to a Channel Master CM3412 distribution amplifier and the outputs of the distribution amplifier will connect to coaxes that go to the tv's. Here is how to aim antennas ,

The digital channels that will be received are the Current Plus Pending Applications Included , Digital Only Stations/Channels in the green and yellow reception zones and some of the tv stations/channels in the red reception zones of the tvfool radar report. . You will make a simple modifaction to the U4000 , you will lift the metal clips that hold the reflector rods in the horizontal position and turn the reflector rods so the reflector rods are more in the vertical position , this gets the reflector rods out of the way so the >< shaped metal reception elements can receive at the back and front of the antenna.
