This is a simulation of the DB4e antenna pattern with the reflector removed. Most other 4-Bay antennas would be similar:



Since the antenna is now bi-directional, the gain will be reduced by about 3 dB.

If you combine two CS2 antennas side by side, you get a CS4. The CS4 has more gain, but the beamwidth is more narrow; there is no free lunch.



Antennas Direct used to publish technical documents that showed antenna patterns. I couldn't find one for the C4MAX, so I had to create this simulation:



Since the C4MAX doesn't have a reflector, its pattern is bi-directional and the gain will be about 3 dB less than indicated for the C4.
