I have a similar one here for use in UK. It does work but the attached aerial is useless, unless you have a TV transmitter in your back garden! You nearly always need to connect to an outdoor aerial in order to get a watchable picture. Otherwise you lose signal altogether or get pixilated or frozen picture.
BTW it doesn't pick up satellite signals - only digital terrestrial channels. There are more expensive units for free-to-air satellite channels which you connect to a dish.
I bought mine for around £20 a while ago. Cheapest starts around £15. Mine is branded MSI.
