A communication system (200) is formed of a base station comprising a main base station receiver with a main base station antenna (202) and a secondary receiver with a secondary antenna (212). The secondary receiver detects interference to the main base station antenna (202) causing reduced communications range for communicating with subscriber units (204). The secondary receiver rotates a receiver null (228) of the secondary antenna (212) to reduce the interference in response thereto. The communication system (200) performs a voting decision that selects between the secondary receiver with rotated receiver null and the main base station receiver (104) with reduced communications range, to mitigate the interference to main base station antenna (102).
