Back has coax, rj45, and power. All the hook up diagrams show antenna to coax, but says
8-VSB (ATSC over-the-air digital TV)
QAM64/256 (unencrypted digital cable TV)
100baseTX high speed network
So if anybody still had unencrypted cable I guess they could plug it in for some channels, but one coax in mean broadcast or cable, not both.
I have a Homerun Prime and TWC which means you need an adapter box and cablecard for just about anything.
