No , the SD receivers do not have any TV tuners.

I would recommend you get a digital converter box at a minimum.
That will only give you standard definition video to your beautiful 42" TV, so it'll be a little underwhelming.
I'm not aware of any VCRs with ATSC (digital) tuners.
There are some DVD recorders with 'em, though.
Again, verify the tuner puts out HD and not just SD!
For best quality, you might consider an HD FTA receiver with an ATSC tuner (very few around) or maybe a DishNetwork (bite your tongue) receiver. -
If you are -very- lucky, you might find an ATSC tuner with Component or HDMI output, but those are pretty rare these days.
They used to be offered at outrageous prices a few years ago.
Now, the ATSC tuner is built into all TV sets, and video monitors are pretty rare.
* edit:
I thought you said Coolsat 4000, but I'll look up the
Sonicview to double check.
It's out of production. I did find the manual (
PDF), and it appears to be typical design for its era.
The antenna input simply passes the signal through to your TV tuner.
That would mean in FTA Mode, the Sonicview would put out FTA programming to your TV on channel three.
Not a very high quality mode.
