Satellite Antenna Alignment is a program that might come in handy when installing satellite dishes. With its help, you can calculate the angles necessary for installing satellite dishes.
The utility doesn't bring you a built-in help manual, but you can find plenty of useful hints and usage instructions on the homepage of the developer.
Once you select the proper calculation items, you can save the offered data to your local directories. You can also copy the results to your clipboard.
Considering I don't know much about satellite dish installment, there's not much more I can say about this program. Based on my test results, the utility works great. However, I can't say I'm 100% positive that the results are accurate. Even the developer says on its homepage that the tool "makes a purely theoretical calculation according to formulas"; so, elements such as trees, landscape or altitude aren't taken into account when calculating the angles.
So, you should first test the trial version of the product, check how it works and if the results are correct, and then decide if it's worth buying Satellite Antenna Alignment for your Windows PC or not.
