Hi there, I have a 120cm dish pointing towards 19.2E. I want to set a another 2 LNBs pointing at 28.2E and if possible 5.0W. I am a novice so I have no idea how to align the second and third LNB (that if dish does not need to be realigned). Do you get some measurments from somewhere with the distances/angles or u use a satmeter (but then again how do u know that the signal you're receiving is the one from the right satellite???) Many thanks!!!
