Systems and methods are provided for redundant antenna systems and methods of managing the power allocated thereto. A redundant antenna system comprises a first antenna array and a second antenna array, wherein each of the first and second antenna arrays are oriented to transmit downlink signals to different geographic areas. A first set of antenna elements of the first antenna array and a second set of antenna elements of the second antenna array are powered by a common power supply. In a normal operating mode, the power supply only powers the first set of antenna elements and in aspects of a redundant operating mode used to serve a degraded geographic service area, the power supply powers both the first set of antenna elements and the second set of antenna elements.
