Base station antennas having radomes that reduce coupling between columns of radiating elements of a multi-column array

A base station antenna, comprising:

• a reflector;
• a multi-column antenna array that extends forwardly from the reflector;
• and
• a radome that is positioned in front of the multi-column array,
• wherein the radome includes a plurality of laterally spaced-apart peak segments that project outwardly away from the multi-column array.

A base station antenna, comprising:

• a reflector;
• a multi-column antenna array that extends forwardly from the reflector;
• and
• a radome that is positioned in front of the multi-column array,
• wherein the radome includes a plurality of longitudinally extending segments that are aligned in front of respective columns of the multi-column array, where each longitudinally-extending segment has a transverse cross-section that includes sub-segments that are at different front-to-back distances from the reflector.
