Birdog meters are distributed by Perfect 10 Satellite Distributing of Arkansas. The devices are used to locate the position of satellites in the sky and aim a receiver dish appropriately to receive the signal. Birdog meters are often used by satellite receiver installation technicians. Along with aiming the receiving dish, the meters establish the strength of the signal and the signal-to-noise ratio–both of which are useful in determining the quality of the satellite signal. The meter is designed to be used in the field and has simple operational controls.
