[QUOTE="RimaNTSS, post: 906074, member: 312276"] Good plan, but... not easy realizable :mad: Are you pretty sure that new holder holds LNB high/low enough? What if real antenna's focus (Green dot) is not located on your LNB's axe? Than you will never be abbe to place LNB in proper place. Moreover, after each 10mm of movement of LNB, you will probably also need to slightly adjust LNB tilt. And finally, are you going to check signal level on some particular frequency? Horizontal or vertical polarization? Low/high frequency? So, I am again back to formula "MMCPP": - Make sure your antenna not warped; - Measure it carefully; - Calculate position of Focal point; - Place LNB exactly in focal point, so LNB's phase center is co-located with antenna's Focal point; - Point LNB to G-spot (give it correct angle).
