This makes no sense. I spent 2 hours yesterday testing with two different lnbf circular and I could only get 48% on nimiq1 (again, if I move the lnbf in my hand closer to the dish, I get around 78%max). However on my 18inches I get 100%. This is way past curiosity, beyond interest, this is more like trying to get a hair to stand on its tip.
Last step is to get an installer (more money) to prove that my dish is the isssue and then I go back to the store and try to get a swap (with hopefully a working one) or maybe they will require to ship it to Fortec therefore I will need to pay shipping (more money).
