It's not 100% clear from your description, but the AF11x is using both
polarities.
The Mimosa is a very strange duck. Even using 2 channels and 2
polarities, there is no way to actually run it full duplex. The
high-latency half duplex is pretty much baked in. IMO, it squanders air
bandwidth at the expense of cheapness. And it's highest modulation rate
is still only 256QAM. We had serious trouble trying to even get 256QAM
on a relatively modest distance link.

I will take a crack at it... just to make sure that My understanding
is correct too.
In licensed radio world, the default lingo is as follows:-
A single channel is actually two channels, one channel is used to
Transmit and the other channel is used to receive.
and each of these channels pair can be either in V polarity or H
polarity (but not mingled).
XPIC is used to describe a radio where you can mount two radios
together, one using the H polarity and the other using V polarity, but
the same channel...
But still only one channel (H + V) is used to transmit and the other
channel is used to Receive. (Thus Full duplex)
MIMO...., = One Channel, both H & V polarities are used, and either
one can be used for Tx and Rx (thus half duplex)
AF11x = Traditional Licensed radio... one channel/polarity for TX
and one channel/polarity for RX
Mimosa B11 = Disruptive... a very odd animal... can be configured as...
Use one channel (both
polarities) for TX and one channel (both polarities) for RX
or ... Use Two Channels, both polarities
in each channel, and use either one to TX & RX (more like a dual
channel MIMO)
AF5 = Uses one channel (both polarities) for Tx and one channel
(both polarities) for RX
AF24 = can be used as
One Channel (Dual Polarities) for
TX and one Channel (Dual Polarities) for RX
or can use the same one channel
(dual polarities) for Tx and Rx.
Hope this is as clear as mud !

What's so much different between XPIC and MIMO? I'm asking because
I guess I'm just ignorant. MIMO = single carrier (is OFDM
implied?), dual streams? And XPIC = dual carriers (is
single-carrier QAM per channel implied?) and independent streams
that are aggregated in hardware, perhaps as simple as a LAG on the
internal switch? Or does XPIC add some more magic?
So then what is the UBNT AF11X considered? Or the AF5 and 24 for
that matter since they're also capable of FDD.

sensitive enough where the X-pol isolation isn't sufficient?
Okay, a vendor can if they're more technical than salesy.
I'm not meaning to imply John was salesy.

Hi Ken, the Lynx and Orion are largely identical. The biggest
difference between the two is that the Orion supports XPIC
where as the Lynx does not. Keep in mind that either model
can be set up for 2+0, but only with the Orion can both radios
operate on the same channel. Other than that, the Orion does
offer higher TX power (for certain frequencies) compared to
the Lynx. However with 6 GHz, the TX frequency for Lynx and
Orion are the same. Orion also features SynchE/1588
functionality which is not found on the Lynx. Both models now
support buffer size up to 8 MB.

Jeremy, I’m trying to remember, can you upgrade that Lynx
to 2+0 with a license key as long as you don’t need XPIC?
Trango doesn’t spell it out very well on their website,
but it looks like the major differences between Lynx and
Orion are buffer size, XPIC, and maybe the interface and
powering options? So that you could still double the
throughput as long as you can license a different
frequency pair for the other polarization. And the issue
of the wired interface speed.

I don't know who has the biggest or best, but my 6GHz
Trango Apex Lynx has been rock solid for going on four
years now. It does 700Mbps FDX. I believe that the
Trango Orion has XPIC up to 1.5Gbps in a 56Mhz channel.

First I have to find out if there are channels
in this area.
Then I have a passive repeater to deal with...

Well you can only use 60MHz channels max. That
helps make it more competitive.
6GHz most likely precludes higher modulations…
you just won’t have the link budget. Also
depends if you’re going all outdoor or
split-mount/all-indoor.
I’d be shocked if there is a winner here – I’d
go with the solution your most comfortable with.
My guess is you will end up with
Ceragon/Cambium or SIAE. DragonWave Harmony
Advanced is certainly worth a look, although
I’m not sure about 6GHz availability since it
just started shipping.
Chuck feel free to contact me offlist and we
could look at some things.
