Why can't I get local channels?

find out where the transmitting tower is and point the antenna that way, then reset the channels. You might improve things more also with better quality coax. og worked with middling strength signals, but digital requires stronger signals. If your reception was decent for ogue, your antenna should be adequate for digital as long as the transmitting tower is close enough and transmitting power of the station is reasonably strong. 20 million watts is good for 15-20 miles.
