pretty much accurate, Doug, except for this:
"...you probably will NOT receive OTA reception unless you have a roof top powerfull Digital type antenna..."
there is no such thing as a 'Digital type antenna'. the OTA antenna, roof, rabbit ears, etc. you were using the day before analog TV went dark is the same antenna you could use the next day to receive digital transmissions. TV antennas are designed for a specific frequency range and not modes of transmissions. the TV receiver (your TV set) decodes the transmissions and displays the picture.
