Patent US 5,589,841

A satellite dish antenna for receiving a broadcast signal from a satellite includes a low noise block which receives the signal reflected from the dish and provides a human-perceptible guidance signal, such as a sequence of beep tones, to aid an individual in properly orienting the satellite dish with respect to the satellite. A time interval between the beep tones is varied in dependence on the strength of the broadcast signal received at the low noise block. A circuit for providing the guidance signal is activated by a non-contact switch, such as a magnetic lead switch. A magnet is movably mounted on the surface of the low noise block for selectively activating and deactivating the guidance signal circuit.
