Sorry wasn't clear enough, it supports both standards but DVB-T2 is the common standard and DVB-T, at least in our country (Austria), was shutdown a few years ago.
Anyways, you can try the card but I don't think it will be recognized.
Yes, but keep in mind they can drop the connection sometimes depending on the motherboard that you are using it with, a few pages back I think a user had such an issue with a AMD motherboard.
I recommend using PCIe based cards, but USB Tuners should also work normally.
Don't know if you can get DVBSky or TBS Cards where you live but I've picked up a Dual Tuner DVBSky DVB-T2/C Card for cheap at the local used market (Euro ~30,-)
