Some, however, do suffer from many of the same design limitations as the less costly converter boxes, including poorly designed signal strength meters, incomplete display of broadcast program information, incompatibility with antenna rotators or CEA-909 smart antennas and inability to add digital channels without wiping out all existing channels and rescanning the entire band.
