and still not sure

I wish someone would make a chart showing the max of each radio per

options. Like some kind of apples to apples comparisons for these
different radios per BW channel size.

Yeah, but to use the same channels that a SAF lumina is using, you
wouldn't be able to transmit on both channels... you'd have to use FD
mode, which if I remember right, means you'd also have to use a fixed
traffic split (although I may be wrong on that... ), so you're going
to get more like 300Mbps, at best. But since it's MIMO, that still
wouldn't be using the same channels anyway... if the B11 could run in
SISO mode, then you'd have to cut that in half again.
But since Paul said there were sufficient channels available to
license, none of that is really relevant anyway.
If it were my link, I think I'd look into what it would take to adapt
the B11's to the existing dishes... if that could be done fairly
cheaply, then I would more than likely just go with the B11's...
especially if I already had them. If using B11's with those dishes is
going to be too costly or too much of a pain, then I'd look at other
options. If you don't have to replace, remount and realign the dishes,
you can spend a lot more on radios and still come out ahead.
I probably wouldn't use AF11's on this link, because they need to be
able to do 1024qam to match the capacity of most 256qam radios, and if
the SAFs can't do 256qam on this link, it's a pretty safe bet that an
AF11 isn't going to be able to do 1024qam.

A B11 can transmit on both channels simultaneously in the same
direction and it’s MIMO.

Well, no, a B11 wouldn't get more capacity using the same
channels... I'm pretty sure it would do quite a bit less,
actually. We're assuming he'd be able to license new channels.

If he wants to keep his existing FDD band plan license and channel
sizes, I don't see how a B11 would be any more capacity at all,
since it would be replacing a 256QAM radio link with a 256QAM
radio link. The B11 is only high capacity when you give it huge
channel sizes or let it do its special weird pseudo-FDD band plan.

B11's are going to get you the most capacity for the least
amount of money, but don't expect them to be as stable as the
SAF link. I've been pretty happy with our AF-11FX link, but
you're only going to get around double the capacity you have
now, and I don't know if there's currently a way to do
multiples on one dish... it might make more sense to do like
Lewis suggested and add a second Lumina.
There are lots of options for higher capacity licensed links,
but they start to get pricey.
You could probably get Chuck to make you some adapters to hook
up just about anything to the SAF dishes.

We have a 4 year old Lumina link from our core, 12.9
miles, 11Ghz with 3ft dishes on each end, that doesn’t
have enough BW for us long term, as we are going to do
another hop from there (7.3 miles), then FTTH.
I get around 270Mbit from it, and we already use 120Mit
pretty consistently and if another tower OSPFs to it, more
than that. Sooo, I am looking for alternatives. Its
mainly one-way traffic of course, so a solution that
favored that would be acceptable.
Cost is a factor of course, as I also have a “parallel
path” a few miles south to do the same on very soon.
Something that could use the same dishes from the SAF
would be good also.
I have some undeployed Mimosa B11’s that we bought for a
project and are still waiting on some tower rights to get
settled. I could use those, or maybe AF-11X or multiples
thereof. I might as well plan for the future since this
is a “main artery” link. We have sufficient 11 Ghz
channels available to license.
Thoughts and suggestions are appreciated !
