I also agree that this is probably the most difficult part of installation and deployment of this type of equipment.
We are currently working on cnArcher, which is an Android app that will help with alignment. We will do some videos and webinars around the use of this new tool to help with this exact stuff. There is a thread here asking folks to be beta testers for this app. We should be ready soon to start these trials.
What Ray links to above is a good lesson for the AP side of things, but I suspect you're looking more for aligning the SMs. The reflector dish narrows the beam to about 6 degrees in both azimuth and elevation, which inherently makes alignment more difficult. It is counterintuitive, and almost appears you're aligning the dish into the ground, because everyone is used to seeing the satellites that point to the sky.
Most installers, though not all, prefer using the alignment tone the radio puts out to find the best signal strength. However, there are instances where signal strength is not the only parameter that matters (i.e. multipath scenarios).
There are plenty of other users willing to share their experiences and tips and tricks for installation and alignment with the community.
If you'd like to continue this discussion, I am happy to, and I will move these last few to a new thread...
