She needs an aerial plugged into the card. Type of aerial and its location will depend on the signal strength in the area where she lives. Look at nearby locals and see what they use for their TV aerials. She may or may not need a freeview box in order to receive the free digital channels, but this depends on the model of the TV card. Do you know the manufacturer/model ? The analogue terrestrial channels will definitely be avaible with no further hardware apart rom the aerial.
