The latest innovation in terrestrial TV antennas, the Smart Antenna (SA), when used with a compatible converter box, automatically adjusts the gain and directionality of the antenna to meet the reception needs of that particular channel.
Digital signals are different from regular, analog TV signals. They require precise directional reception to give you consistent performance. This means your antenna needs to be aimed in exactly the right direction to give you uninterrupted, crystal-clear digital picture and sound.
Why not use an antenna made specifically for digital TV? There is a new antenna design that eliminates the guesswork in digital reception, finding and delivering great digital picture and sound without the hassle of manual adjustments.
The antennas remove the burden of positioning an antenna or rabbit ears and can make the tuning process EZ!
These antennas can only be used with your Digital (ATSC) TV or with a Digital Converter Box that has a SA interface.

Update: These antennas were widely sold for a short period of time, but now as far as we know they are not being manufactured and are very hard to find.
Amazon.com occasionally sells these models,
but they are usually used products
