Ditto. Same for sectors or dishes. Most of the time on Backhauls I can see the other side enough to recognize it through binoculars. If not I use the Google Earth method there too. When done I use my phone to take a photo with the phone pressed against the top rear of the sector so that they are aligned. From the photo you can see where the center is pointing. Some dishes will do the same if there is enough lip to do it.
