I am experimenting with some 3 Ghz antennas. I have a 2 way power divider feeding two 120 degree sector antennas rated at 15 dBi each. I have a 11 dBi omni that I am comparing it too. It seems the omni is getting better performance then the array is. I am seeing more than a 4 dB difference, loss. My goal is to get more down tilt in my antenna pattern, as the sectors offer a mechanical down tilt.
Am I doing something wrong? I am feeding the antennas with LMR400 and feed is short as possible. Each feed from the divider is 15 inches long to the antenna. The insertion loss in the divider is <0.4 dBi according to the spec sheet. Thanks in advance, Matthew
