Just Trying to Clarify Things for the OP...

SURE it matters!
A 'Channel Scan' on Cable or FiOS will detect SEVERAL ClearQAM channels while, AFAIK (never having used Satellite) a 'Channel Scan' on a Satellite STB will only detect the RF3/4 NTSC (and display whatever content the Satellite STB is currently tuned to). So why waste 15+ minutes scanning? Just manually tune to NTSC 3/4.
I just wanted to point out to the OP that, IMHO, Otto Pylot's
suggestion didn't seem very useful. If you have a SD STB (WAG since there's no HDMI output), whether Cable, FiOS or Satellite, you're going to get SD. If you want HD, you're (i.e. the OP) going to need a HD STB with HDMI and/or Component outputs. IIRC, S-Video and Composite will usually display a 'Postage Stamp' 16:9, requiring a ZOOM, instead of a Full Screen of data bits.
I'm over 60 and just watching TV has become 'so interesting
' since the introduction of ATSC to OTA *AND* the subsequent, NON- MANDATORY follow-up by Cable to dump NTSC, constantly shuffle the PSIP data for the ClearQAM channels, and thus, for 'Joe Public', require a STB / $$$ for *EACH* TV, DVR, VCR, yada, yada, yada...
