So yeah like he said you can measure the elevation angle pretty well
with a cheap tool. You align the first dish's azimuth to a landmark and
dead reckoning. You peak the second dish, then go back to peak the
first one.
If the tool lets you nail the azimuth on the first dish without
re-climbing the tower then it's worth every penny. Does it? Just
wondering.
If you use backhauls with the BNC voltage output and get the BNC to
banana plug adapter then you get realtime feedback to peak the signal
with. I always thought the scope thing was a good idea, but never did
get to use one.

We have one and it's very nice. We only use it to aim sectors and
horns. For backhaul dishes, there no need to use it in my opinion
since we use landmarks to get the aiming started. With sectors,
there's no way to aim it like a dish so this tool is very helpful.
It should be under $4600 as that's what we paid for it new.

Not trivial because the baseline between the two GPS receivers is
very short.
Maybe I will finish it someday.
If you buy one, let me “borrow it for a few days”...
Elevation is very simple. You can buy a cheap electronic level
from any hardware store to nail the elevation.
Then all you gotta do is sweep and peak.
I have not talked to anyone that has used one of these things.
If you can find a landmark along the path and use a scope for
azimuth you will be dead on for a lot less money.

I got approval from the boss to order a smart aligner. Ive been
looking at this for a while, particularly with the need for
accuracy in CBRS. Not looking to use it at customer sites, just
backhauls and access points.
We have historically never been verifiably accurate on azimuths,
probably rolled out pretty bad too. We have had issues with
contractors not installing sites to spec, and having to go back up
to turn radios/adjust tilt, etc.
This will be handy for this year, we are dropping in at least 40
new access points and 3 or 5 new licensed links in the next few
months. but then the tool will sit
Boss said the worst thing to me, "get it if you think its
necessary". If it were a $1k tool it wouldnt be a question bet we
are looking at almost 7k on the kit. It meets my accuracy needs,
but I almost wonder if the convenience outweighs the necessary.
ant his is over half the cost of a licensed link.
Knowing my numbers are right in propagation tools holds a lot of
value. saving maybe an hour getting a tight link aligned here and
there offsets some cost.
You old timers, is this a justifiable expenditure based on your
experience?
