This makes some optimistic assumptions about the OP's telephony capabilities. An installer worth their weight in pigeon droppings should have a much more trustworthy solution (inclinometer). Experience in the region doesn't hurt either.
I don't own a smart phone and I've never seen one that had the DishPointer application installed on it. I have little doubt that it is a great tool, but the support equipment is a lot expensive if you don't already have such a phone (or an iPod Touch -- I don't have one of those either).
Chip,
That app is better than a clinometer / compass! It also shows background LOS problems. So you see the sats and the trees,buildings and hills that block the signal. I thought the laser pointers were great but the picture is worth...about twenty minutes of BS with a cx who will not hear. Especially when it often turns out the cx does not own the ground where the blockage lies.

Harshness, so first you claim that a smartphone app isn't as good as an inclinometer, then you say you have never even used one! Care to explain to those of us who have, including the above quoted installer, how you know better than we do?
