ant power on ZGemma H2H - switch it off for cable

I just set up my H2H for VM and got most channels but didnt pick up some channels like sports 5 HD sat here scratching my head, thinking is cable tuner faulty, cable faulty had another look on back of the box and saw the Ant Power was On so turned it to Off did another scan and all channels picked up, so just a heads up to people who may have problems getting some channels
