Recognized for its usage in radar and cellular antenna systems, Smart antenna technologies are a significant innovation for terrestrial users because they vary and adjust themselves dependent on environmental conditions. The major benefit to you is that in most cases, the use of this antenna will capture more local channels in your area. Here is a description of how each type of antenna works:

•    Adaptive array – (typically an outdoor antenna) Beam patterns adjust automatically as interference changes or moves therefore providing a more pure signal; multiple antenna elements from an outdoor antenna receive signals in a 360 degree fashion. They are weighted then combined, maximizing the desired signal to interference (plus noise) ratio.

•    Phased array – (indoor antenna) A beam, or multiple beams are steered towards or selected from and compared electronically as the antenna is physically moved towards a signals direction, maximizing the desired signal to interference (plus noise) ratio.
