Abstract
A system and method for controlling a television antenna includes an amplifier circuit mounted with the television antenna. The amplifier circuit is connected to the television antenna and a control line. The control line is used for controlling the gain of the amplifier circuit.
Claims7
A system for controlling an exterior television antenna comprising:
- an amplifier circuit mounted on a building exterior with said exterior television antenna and connected to said television antenna;
- a control line extending into an interior of said building, said control line being connected to said amplifier circuit for controlling a gain of said amplifier circuit,
- wherein said control line also provides power for said amplifier circuit wherein said control line carries a control signal which is a direct current (DC) voltage signal comprising a voltage to power said amplifier circuit plus an additional voltage that varies to indicate a desired gain of said amplifier circuit.
A system for controlling an exterior television antenna comprising:
- an amplifier circuit mounted on a building exterior with said exterior television antenna and connected to said television antenna;
- a control line extending into an interior of said building, said control line being connected to said amplifier circuit for controlling a gain of said amplifier circuit wherein said amplifier circuit comprises a voltage controlled amplifier, wherein said amplifier receives power and a voltage controlling a gain of said amplifier over said control line.
A system for controlling an exterior television antenna comprising:
- an amplifier circuit mounted on a building exterior with said exterior television antenna and connected to said television antenna;
- a control line extending into an interior of said building, said control line being connected to said amplifier circuit for controlling a gain of said amplifier circuit wherein:
- said exterior television antenna comprises two or more antenna elements differently oriented;
- said amplifier circuit further comprises two or more amplifiers connected to respective antenna elements;
- and
- said control line provides independent control signals to said amplifiers to selectively adjust a gain of each of said amplifiers to adjust a polarity of said antenna.
