I need a freeview box that has the ability to supply power to an indoor aerial via the coax cable. I used to have a box at one time where you could switch the feature on or off in the setup menu. I have looked through the spec's of many boxes, but none so far list that feature. Can someone point me in the direction of a suitable box please. There won't be a problem with poor signal, as I can see the transmitter mast in the distance out of my window.
