Abstract
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.
Claims10
A satellite antenna comprising:
- a support;
- an antenna assembly adjustably mounted on said support and exhibiting a changeable orientation with respect to a satellite broadcast signal, said assembly including a housing, a low noise amplifier within said housing for receiving and amplifying said satellite broadcast signal, and a dish antenna arranged with respect to said low noise amplifier so as to convergingly reflect said satellite broadcast signal toward said low noise amplifier;
- adjustment guidance means provided within said housing for emitting an adjustment signal that is responsive to a characteristic of said satellite broadcast signal received by said low noise amplifier to provide an indication of the orientation of said antenna assembly;
- a magnetic lead switch provided within said housing for selectively activating said adjustment guidance means;
- and
- a magnet for controlling said magnetic lead switch, said magnet being mounted on a surface of said housing for movement between a first position for activating said adjustment guidance means and a second position for deactivating said adjustment guidance means.
A satellite antenna comprising:
- a support;
- an antenna assembly adjustably mounted on said support and exhibiting a changeable orientation with respect to a satellite broadcast signal, said assembly including a sealed, water-proof housing, a low noise amplifier within said housing for receiving and amplifying said satellite broadcast signal, and a dish antenna arranged with respect to said low noise amplifier so as to convergingly reflect said satellite broadcast signal toward said low noise amplifier;
- adjustment guidance means provided within said housing for emitting an adjustment signal that is responsive to a characteristic of said satellite broadcast signal received by said low noise amplifier to provide an indication of the orientation of said antenna assembly;
- and
- a magnetic lead switch provided within said housing for selectively activating said adjustment guidance means.
A satellite antenna comprising:
- a support;
- an antenna assembly mounted on said support for horizontal rotation and for vertical rotation with respect to said support, said antenna assembly exhibiting a changeable orientation with respect to a satellite broadcast signal, said antenna assembly including a sealed, water-proof housing, a low noise amplifier within said housing for receiving and amplifying said satellite broadcast signal, and a dish antenna arranged with respect to said low noise amplifier so as to convergingly reflect said satellite broadcast signal toward said low noise amplifier;
- an adjustment guidance circuit provided within said housing for emitting an adjustment signal that is responsive to a characteristic of said satellite broadcast signal received by said low noise amplifier to provide an indication of the orientation of said antenna assembly;
- and
- a magnetic lead switch provided within said housing and associated with said adjustment guidance circuit for selectively activating said adjustment guidance circuit.
