Dvb-t2 TV dongle - USA OTA ATSC?

Dvb-t2 TV dongle, osmc branded - exciting!

1 - does this work with USA OTA ATSC?
2 - what is the min spec’d osmc device that’ll handle live TV graceful with this?
3 - may this be plugged direct into an RPI3 or does a USB Hub need to be between the devices? What about an rpi2 & Vero 2?

Does osmc ‘supported’ DVR software support recording to a network or is a local HDD really preferred?

Unfortunately not.

It’s a DVB-T2 dongle
