Connectorised Back Hauls

Can somebody explian the difference between 5.7 Ghz 45 Mbps Backhaul Connectorised Unit and the normal one, that is not designated as “connectorised”

The integrated units have a panle antenna attatched - 23.5 dbi gain and 8 degree beamwidth. the connectorized units have two N-female connectors onthe bottom for using external antennas (the 45 Mbps backhauls actually have two transmitters and two receivers). One set are horizontally polarized and the other are vertically polarized.

If you link can not be usable with the integrated antennas you can use external antennas (dishes in most cases) to increase the gain and even to add space diversity for reliability.
