[QUOTE="BombedOne, post: 600123, member: 300998"] And also, it will be interesting to estimate, what gain loss I will face, and what advantages this dish in general will give to me... For example, by having 1.2m dish with 42db gain, I can ONLY receive wide beam of Astra 1M. Using 1.5m dish with 43db gain I can receive almost all european TPs from 1M, and even some TPs from 1H, but with quite low level, absolutely no space for bad weather. The declared gain of 1251 is 47.6db. Say, due to deformation and aging it had lost 2.6db and now has 45db. Currently, when comparing 42db and 43db dishes, I achieve average 15% increase in signal Q. If follow that methodics, I should expect 45% more Q on 1251, compared to 1.2m one or not? I mean, is actual signal increase linear, or logaritmhic, or any other formula? [/QUOTE]
