A Diversity Antenna system has two, or more, antenna which are mounted on a vehicle. The system will select which antenna to take the radio or other device, signal (AM, FM, WiFi, satellite, microwaves, mobile phones), from depending on which one is receiving the clearest signal - also known as best Signal to Noise Ration (SNR). Users should experience less static and fewer weak audio signals from obstructions like buildings, traffic lights or power lines.
