[QUOTE="Trust, post: 970985, member: 181524"] I'm not allowed to go to the shed , so did some research at the desk . Found out that there is something wierd with that russian parabola calculator . Changing the dept values from 1 to 1000 mm does not effect the calculated offset angle at all , that cant be right . I found another parabola calculator at [URL='http://www.electronicecircuits.com/electronic-software/parabola-calculator-for-satellite-dish-antenna-design']Parabola Calculator for Satellite Dish Antenna Design | Electronic Circuits[/URL] For offset dishes you have to choose the wifi version , there is a option for extra data if the deepest point of the dish is out of centre . I know at Triax dishes that point is below centre , I dont know for the Laminas AS-1800 . With that calculator by 1935 x 1800 x 170 (centre) the offset is 22.5º Do I change the dept in that calculation , the offset angle change too . [ATTACH=full]93135[/ATTACH] [/QUOTE]
