[QUOTE="RimaNTSS, post: 1027278, member: 312276"] Without knowing the depth of the dish (with the precision up to 0.1mm) it is impossible to tell location of "F". Wide and high can only give you such an important parameter of the dish as it's offset angle, which in your antenna case is 27* (if 980x1100mm is correct size of the working area). So, there we see mismatch of the offset angle you mentioned earlier and calculated one. Added later: But what is funny..... producer claims the working area of the [URL='http://www.triax.com/products/satellite/satellite-dishes/steel-dishes/td110-std-ral-7016-50-pcs-bulk-pack-wing-nut']TD110[/URL] 1000x1100mm which would give an offset angle 24.6*, but, at the same time they announce an offset angle of this dish to be 26*! That tells something about professionalism of the TRIAX company as such! At least I have this impression. And, in addition to this, they make such a stupid adjustment mechanisms to their antennas that makes tuning process very painful. Add #2: If there is change of the signal that means you had elevation set not properly. After all those mismatches do you still believe manufacturer could place LNB-holder in the right position? I would not be so optimistic. Usually it is because there are variations of the signal level during the day and also depends on the weather conditions. Another reason for such a variations could be fact that dish is not tuned properly. [/QUOTE]
