TVs can't tune satellite signals either. There are three basic modulation schemes:
satellite: DVB/DVB-S2 and QPSK/8PSK
OTA (ATSC): 8VSB
Digital PC tuners and newer digital TVs usually support 8VSB and QAM, but none support the modulation schemes used by satellite.
Now, it is possible for a building to take certain channels from satellite and modulate them into NTSC or QAM for customers. If your building does that, then your PC tuner would probably work. If your TV can tune the channels, then so will your PC card.
