  • Publication number: 20110111715
    Abstract: In an exemplary embodiment, an outdoor unit of an antenna system includes an audio device that generates a sound that aids in the aiming of the antenna system. The sound is based on the strength of the received signal. Furthermore, in an exemplary embodiment, the sound indicates the signal strength using tone, pitch, repetition, volume, and the like. This sound can be used by a person to aim an antenna system in order to receive a better signal. The person installing the antenna system can be a professional installer, a layperson, or the consumer because the installer does not require any special skills or equipment.
