Smart Antennas are directional antennas that are "smart" because they automatically rotate to the proper direction depending on the location of the channel you’re watching. The smart antenna works best if used with only one TV and converter box at a time, because the “smart” technology is designed to capture the best signal for the TV that is plugged into the smart antenna port (EIA/CEA-909 interface).
Technically you CAN attach more than one TV to the smart antenna. But, if you use a splitter to attach a second TV and Converter box, your smart antenna will only adjust itself to accommodate the first TV. So you may experience sub-par reception on your second TV when viewing stations from a different direction than the first TV.
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&. thats a lot of pointing with your old antenna! Why not use an antenna made specifically for digital TV? RCAs unique and patented antenna design eliminate the guess work in digital reception, finding and delivering great digital picture and sound without the hassle of manual adjustments.
Analog televisions generally give instant feedback as the signal gets better or worse as you move the antenna. Digital television antennas can be difficult to aim correctly because of delays in decoding and displaying the signal. Smart antennas remove the burden of positioning the antenna for digital TVs and can make the tuning process easier than it was with analog television. Be amazed at how many new free digital channels you will discover when this product is used with your digital capable television or on old analog sets with a Digital Converter box.
