The Directv high definition receiver is all you will ever need for complete HDTV reception. Not only does it receive satellite HDTV it also receives over the air HDTV if you connect an antenna to it.

Incidentally, there is no such thing as a high definition antenna, any regular UHV/VHF antenna is absolutely perfect.
