This might be an option for some of my installations where I have few clients per AP. Can you clarify which connections on an ePMP4600 are which chains? The ePMP4600 has 4 connectors on it and currently we connect all four of those to a single 90 degree panel antenna Cambium PN C060940D301A.
Thanks.

Has anyone gotten this working with the 4600 on two horns pointed in two different directions? If so, would that be considered “Omni” Downlink antenna in the gui with MU-MIMO enabled?
