This device includes 2 digital terrestrial TV turners able to work together in order to deliver an optimized and enhanced sensitivity.
Elgato being a German company, they even advertise that one can use it in a car speeding up to 160km/h on the motorway ;)
This device will also allow you to watch a TV show while recording simultaneously another one (you will need 2 antenna).
