Base stations including base station antennas having multi-beam antenna arrays that are configured to operate with radios having different maximum output power levels

A cellular base station, comprising:

• a base station antenna that comprises:
• a first set of radio frequency (“RF”) ports that has a total of N first polarization RF ports, where N is an integer that is greater than 2;
• a first multi-column array of radiating elements that is configured to generate N first polarization antenna beams, the N first polarization antenna beams including a first pair of outer first polarization antenna beams and a first inner first polarization antenna beam;
• a first beamforming network that electrically connects the first set of RF ports to the first multi-column array of radiating elements;
• a first radio that has a first radio port that is coupled to a first of the N first polarization RF ports in the first set of RF ports, the first radio having a first maximum output power level;
• and
• a second radio that has a first radio port that is coupled to a second of the N first polarization RF ports in the first set of RF ports, the second radio having a second maximum output power level that is greater than the first maximum output power level.
