When the Dish Network installer originally installed my satellite dish he had to install it on a free-standing pole due to condo rules. The setup he used was pretty poor and included some patio blockes leaned against the post to steady it.
I had noticed some more frequent drop-outs and decided to install a more rigid post. I needed something to re-aim the satellite dish once I did that. I used the aimer to do the initial aiming of the dish. It really helps that it has both a tone that changes in volume with the aiming and a meter reading.
I did find that I still had to make final adjustment of the satellite dish pointing using the TV set and the Dish reveiver in "install mode". That was tedious and not at the peak the meter gave me. On the other hand the meter got me close enough to be able to peak the dish using the TV display from where the meter got me initially.
For the price its a great little tool!
