You need to connect the Terk to the muiltiswitch and use a diplexer at the receiver end to pick off the OTA signal and route it to the TV. The Terk is not a very good antenna, but depending on your location it might work. If not, a real antenna would probably help, particularly with digital signals.
For a HR22 you need a 5 LNB Slimline dish with a WB68 switch. The WB68 dosen't have a port for TV antennas. The HR22 also dosen't have an ATSC tuner built in you need an AM21 to tune OTA. Information from Timbug's post of same question in OTA forum.
