Okay, good. That's exactly what I did. I assumed the beamforming
capability was limited to the non-dish models. I didn't think you
could beamform when a dish is involved, so this is good to know.
Thanks!

I've found that it works best to just align them visually
using the little plastic sight that comes with them. It
doesn't really work very will to use signal level to align
the Mikrotik 60ghz stuff, because of the beam forming... the
arrows work fairly well, but it does seem to be almost
impossible to get it right on using those. The beam
forming does seem to work pretty well on them though, so they
don't need to be terribly precise... it's not at all like
trying to align something like the Ignitenets.

I'm wondering if any of you have pointers for aligning
these things. Do you just use the little arrow LEDs on
the radio? I tried doing that but never could get them to
all go out. When an arrow would light up, I'd move it
that direction (very slowly), but I'd invariably
overshoot, and the opposite arrow would come on, or in
some cases, while adjusting horizontally, I'd suddenly
get a vertical arrow lighting up that wasn't there
before. I finally gave up and left it with a couple
arrows on. It's running at full capacity, but if the
signal isn't maxed out, I worry what will happen when
there's a downpour. Any advice?

I'll have to look at them again, but I think the
mounts are basically the same as the solid mounts for
the old wireless wire dishes. I haven't had any
problems with the alignment adjuster screws seizing
on any of those, and I've used quite a few of them,
but the u-bolts can certainly be a problem... But
that's easily fixed by just replacing the nuts with
something other than stainless. I've gotten into the
habit of just automatically replacing the nuts any
time I see stainless hardware, or greasing it, if I
have to.

Guessing when you say the new Mikrotik
variant, you're talking about the nRay. I
just picked up a pair of those for a link of
about 250 ft. One issue I had with them is
that the mount is all stainless steel
hardware, and about 10 minutes after slightly
tightening everything up, I found all the
nuts were seized and I could no longer loosen
it without breaking bolts. Even the alignment
adjuster screws have this issue. I noticed
everything was stainless before I started
installing and should have just waited until
I could get some non-stainless nuts to
replace the stainless ones. But being the
impatient idiot that I am, I decided I just
wouldn't tighten them down too much, and then
I'd pick up new hardware the next time I came
back. Now, I'm looking at having to buy new
mounts for both ends. Why do manufacturers
use all stainless hardware? When I owned my
WISP, we had this issue way back in the
SmartBridge days (early 2000s). Seems like
manufacturers should know better.

The Mikrotiks are by far the easiest to

tried, and I think they're probably the
most reliable too. I have a set of the
new variant sitting here, and they look
to be an improvement, but I haven't tried
them yet. They would be my first choice
for super short links.
I had high hopes for the Cambium 60ghz,
but unfortunately it looks like they only
support up to channel 4 (64.8ghz), which
means they won't have significantly
different range than the Mikrotiks, but
if you need more than 1 gig, they're
likely the best thing out there at the
moment.

The 5ghz backup would have been

The problem is that it has tiny
antennas (8dbi, if I remember
right)... so it really only
worked for really short links
anyway, and even then, it seemed
kind of buggy.

The radios/antennas didn’t
seem to be made for it and it
ends up causing more issues
than it solves IMO.

Seems strange to me that they
dropped the 5GHz backup radio
from the GBE Plus and
the AF60LR. All the other
60GHz radios have a 5GHz
backup of some sort.
We have installed a number of
the little 60GHz GBE radios
and they seem solid for short
links with easy aim.

I think they claim their
"Wave AI" feature is

being able to use
66-70ghz behaves more
like 70/80ghz than the
lower 60ghz band, so you
can do much longer
distances... you still
have the same problem
with rain fade, but even
on something like a 1
mile link that will work
at 64-65ghz, it works a

have more signal to work
with.
