Also note, because regular compass works on magnatism, it will not always
function accurately on top of tall buildings, because of all the other forces
up there that screw with it.
So usually, we print a map, draw a line, and look for landmarks, and calculate
the degree to a specific landmark, therefore we can align / verify our compass
to that landmark.
GPS compass will work more accurately.
We do almost all our 5.X dish alignments with a single tech, one side at a
time, and we find it quicker (man hours) to do it that way, even when a second
trip is needed to the first site..
If aligning millimeterwave 24Ghz and above, well its like near impossible to do
quickly without two people.

Subject: Re: [WISPA] PtP Dish Alignment
It looks like for around $150 you could get binoculars with a built in
magnetic compass that you see through the binoculars. Could you use the
binoculars to find an object on the horizon on the right azimuth and then point
the dish there?

Question: What tools do you use to blindly put up the first end of a ptp

Details:
When deploying ptp dishes... One team doing both ends at different times.
The first dish must be aligned without a connecting radio at the other end.
We know how to get uptilt/downtilt/azimuth from Radio Mobile.
Uptilt/downtilt is easy to do with a simple gauge. Azimuth is a different
story. If you can see the site that you're aiming for, no big deal, but what
if you can't?
We have a number of backhaul upgrades to do in the next few months, and we
have alot of fog here in the mornings this time of year.
