I didn't think of that if they're using the 2 separate uplink antennas. But I would have thought the scheduler would keep that from happening.
I just forced them both to the smart antenna.  We'll see what happens.

If distance is fluctuating it could be multipath, eliminating that as much as possible will help. but having them on two different uplink antennas may help ensure the AP isnt "blinded" on the uplink. the AP Rx should be pretty much even, if theyre not and one is fluctuating more than the other it may be the multipath culprit. I dont know if theres shrouds for these like ubnt had, but if you have one of the old NSM shrouds you could try affixing it with the gap away from the other radio to shield the two somewhat. It wont fit all the way around but could give you an idea of whether you should go to the machine shop. I dont know if RFArmor is still a thing or not

    Yes, distance is fluctuating.  Right now they're showing equal
    distance.  And both re-reged within 30 seconds of each other 10
    minutes ago.

    Do you mean set the preferred AP?

    Don't have a good way to get vertical separation.

    can also try locking one to the sector

        Is the SM distance fluctuating? Can you
        get vertical separation, 18 inches?

            I have a rooftop that has an existing Force300-25 radio
            on it for
            several months.  I just added a new Force300-25 radio on
            a new mount
            next to it, so they are separated by a few feet
            horizontally.  Both
            radios are now re-associating randomly to the EPMP3000Ap
            with Beam
            Steering Antenna every couple hours.  Has anyone else
            seen this? These
            are the only 2 SM's on the AP that are dropping. In the
            AP wireless
            table, it also thinks that they are 0.5 miles different
            in distance.
            Signal levels are exactly the same.

            I've seen the Signal levels do strange things when EPMP
            SM's are close
            together, but I haven't seen the radios make each other
            drop out before.
