How many of you remember Swedish Microwave? I have an old program from them that calculates azimuth, polarization and elevation when installing a dish. I use it mainly for my stationary dish installations. They now have that calculation online in addition to gain and noise figure calculations. Their main website with the products they offer is at Swedish Microwave. You can navigate to the calculation page by going to the SMW Link page or here is the direct link, SMW Link. Hope this is helpful.
