[QUOTE="RimaNTSS, post: 1072124, member: 312276"] Not really. LNB should be pointed below the center of the dish. In case od Deltastar 120 (Fibo120) the aiming point (Le point "G") is 863mm from the top of the mirror (distance A-G) [ATTACH]124742[/ATTACH] diagram is for CM dishes, but principle is the same. 27.3* offset angle is correct. Your dish become warped over the years of use, that is part of life. Nothing and nobody is perfect. And I am pretty sure, after you fixed the shape, it will become warped back sooner or later (maybe faster than you hope). This issue can be fixed only in radical way.... change the main mirror to another one, for example Channel Master 1.2m or other sturdy shape antenna, which is made of plastic. [/QUOTE]
