[QUOTE="a33, post: 1115601, member: 332642"] That would give about 28.5 degrees offset for the present position of the LNB feedhorn (for focal point about 1.5 cm from the LNB front). Calculation: see of course [URL='http://www.macfh.co.uk/JavaJive/AudioVisualTV/SatelliteTV/SatelliteAnalysisSettings.html']Satellite TV - Scientific Analysis - 2 Dish & Rotor Settings[/URL] (But this is certainly not a preferred method to calculate the offset angle of a dish, but just the method to calculate the present offset position of the LNB; other than Charles Macfarlane wrote there.) I agree that there are questions to ask about the proper LNBposition for this dish. If you want to go further with it, I would do mm-precise measurements on it (height and width), and 1/2 mm-precise measurement on depth at the center; all of course on (the edges of) the working paraboloid surface of the dish... and tested that the dish is actually exactly flatfaced... greetz, A33 [/QUOTE]
