Systems and methods for television antenna operation
View Patent ↗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.
1. 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.
2. 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.
3. The system of claim 1 , wherein said amplifier circuit comprises:
an attenuator connected to and controlled by said control line; and
an amplifier,
wherein said attenuator selectively attenuates a signal from said antenna before providing that signal to said amplifier.
4. The system of claim 3 , wherein said attenuator is voltage controlled.
5. The system of claim 4 , wherein said control line also provides power for said amplifier circuit.
6. 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.
7. The system of claim 6 , wherein said amplifier circuit further comprises a summer for combining signals from said two or more amplifiers.
