On a couple of towers we put strobes on them and put them on the
remote reboot unit. Fire em up from our smart phones when we can't find
the tower for installs and such.

I run up a 3 foot helium balloon and use a pair of binoculars.
Works every time.

I just did a ptp install of 5g 2ft rocket dishs at 6.47 miles and
could not see either tower.
Now I already had a ptp link to another tower from tower 1 so this
helped.
I used Google Earth to map out the points and then used the ruler
to connect each ptp link.
I took the map with me on tower 1 and mounted and aligned the
dish. I just eyeballed the direction of the dish in relation to
the existing dish using the Google map. I got everything powered
up and then went to tower 2.
At tower 2 I had a landmark that I thought was close to the right
direction. Mounted dish and pointed at landmark and had a signal.
I then aligned dish while guy on ground gave signal reports.
I have not gone back up on tower 1 yet to tweak dish. I actually
have a 67 signal when lingowave said it should be 57 so I do need
to align dish on tower 1.
I did not want to believe Google maps at first but when I actually
got up on tower I could tell it was about right.
I have tried using a compass but on a tower the compass will not
work correctly. Guess the metal structure throws the magnetic
field off.

Question: What tools do you use to blindly put up the first end
of a ptp without having a visual on the other side?
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.
