GPS accuracy is questionable
iPhone 15 Pro: gps location changes from time to time, hence not accurate azimuth and elevation. No military bases nearby to gam the signal whatsoever. To calibrate elevation you need to place an iPhone from behind the dish (and see a satellite), according to video instruction, but using satfinder professional device angle turns out to be an opposite (you need to tilt the dish to the ground, not elevate to the sky). Azimuth also turned out to be in opposite direction. Waste of money, IMHO.
