1. A twin beam base station antenna, comprising:
an angled reflector having a first planar panel and a second planar panel that is angled with respect to the first planar panel;
a first array that includes a first plurality of radiating elements that are mounted to extend forwardly from the first planar panel, where the radiating elements extend in three vertically-extending columns, and the radiating elements in the middle of the three vertically-extending columns are vertically offset from the radiating elements in the other two of the three vertically-extending columns;
a second array that includes a second plurality of radiating elements that are mounted to extend forwardly from the second planar panel, where the radiating elements extend in three vertically-extending columns, and the radiating elements in the middle of the three vertically-extending columns are vertically offset from the radiating elements in the other two of the three vertically-extending columns;
a first phase shifter having an input and a plurality of first phase shifter outputs;
a second phase shifter having an input and a plurality of second phase shifter outputs;
wherein more than half of the first phase shifter outputs are connected to respective ones of a plurality of first sub-arrays, where each first sub-array includes a total of one radiating element from each of the three columns in the first array,
wherein more than half of the second phase shifter outputs are connected to respective ones of a plurality of second sub-arrays, where each second sub-array includes a total of one radiating element from each of the three columns in the second array.
