Hello cbs, welcome to PCHF.
I've never thought very much of Belinea. One the posative side they are very cheap, but they are very basic in terms of functionality and I have not found them too reliable.
Popular and reliable makes include: ASUS, Acer, Samsung, SyncMaster (to name a few).
As for the Antenna question. What you need for this is a "TV Tuner". You might as well buy the PC USB version for the price your would pay for a set top box. For example:
MiniHDTV USB TV Tuner,PTV-384-EF
Popular and reliable makes include: Hauppage and Pinnacle.
EDIT: Marked as Resolved.
