Can it handle reception of multiple channels from multiple directions simultaneously? I am guessing that it is similar to the MIMO antennas used for Wifi and cellular, in which case it should be capable of doing just that. I found a small blurb on Wikipedia about this, and apparently there were two such antennas formerly available but neither is being produced anymore. I assume there must be some problem with this in practice, or this type of technology would dominate the market instead of people continuing to use old school antennas which are aimed in a specific direction. I know the MIMO antennas used elsewhere require a fair bit of processing power, and since the SmartAntenna technology you're talking about was designed for the DTV converter boxes, that is to say at the very low end of the market, maybe sufficient amounts of processing power could not be included at the price range they were targeting. With another half decade of ASIC performance increases behind us and Directv presumably willing to make it cost what it needs to cost to get it done right, perhaps this is a possibility.
