If you want to receive the free HDTV signals that are available over the air, you are probably having a problem finding an appropriate tuner unless you are willing to subscribe to cable or satellite and pay for what is free. Humax provides an over the air HDTV tuner that will deliver free programming to your television in any format used in North America from HDTV right down to standard television. You will also find that many channels suddenly provide more content! Who knew that channel 44 in Boston is now broadcasting 4 separate streams. 44-1, 44-2, 44-3 and 44-4 all provide great programming that you will miss without an HDTV receiver. The only down side of this early entry in the HDTV receiver/converter arena is that it will occasionally "hang" and need to be power cycled if it is not locked on a good channel. When you are on a good channel, reception is perfect and the box works great.
