Hi,
According to data sheet Rocket M5 or M2 are compatible with several AirMax Sector and Rocket Dish antennas, but in some remote areas or overseas markets these antennas might not be available.
What would be a general antenna requirements for Rocket M5 or M2 IF I have to adapt to an existing antennas that could be already installed at client's site?
Thank you in advance.

Ubuser, the Rockets are 2X2 MIMO devices. That
means they have two signal 'chains' which are
separate rf signal outputs to isolated antennas.

All the AirMAX antennas consist of two isolated
antennas--one in the horizontal plane, the other
in the vertical--which transmit the two chains.
Isolation between planes must be well over 20dB.

You can substitute your own dual-polarized antenna
if it has at least this much isolation. You could even
use two discrete antennas and rotate them to the
two different planes, if you can maintain isolation.
This means separation and careful placement.

Note the Rockets have RP-SMA female connectors.
Most commercial antennas have N-type female
connectors; you'll need adapter jumpers. Dave
