Patent ID: 7587183

Claim:
A method relating to electrically powering an amplifier of an antenna system operable for amplifying first and second signals having different frequencies, the method comprising: determining whether there is present and activated one or more of a first receiver associated with the first signal and a second receiver associated with the second receiver; electrical powering the amplifier via the first receiver when the first receiver is present and activated; and electrical powering the amplifier via the second receiver when the second receiver is present and activated and when the first receiver is not present and activated; wherein the method includes using a controller to automatically control whether the amplifier receives electrical rower from the first receiver or the second receiver; wherein the method includes using a DC switch to automatically control whether the amplifier receives electrical power from the first receiver or the second receiver; wherein the DC switch includes a first setting in which the amplifier receives electrical power via the first receiver, and a second setting in which the amplifier receives electrical power via the second receiver, and wherein the method includes automatically selecting the first setting for the DC switch when the first receiver is present and activated, and automatically selecting the second setting for the DC switch when the second receiver is present and activated and when the first receiver is not present and activated.
