I have been going mad in trying to get my Gibertini 1.5 to tie up with the maths.
3°W is my zenith sat, it's elevation is 31.6° the Gibertini 1.25 & the 1.5 has an offset value of 21.3° so my dish face has to be 10.3°
Every time I set the dish face to 10.3° I get no signal! So I put the 1.25 on the mount and set it up to 10.3° and bingo I have max signal.
But on the 1.5 dish no signal, so I checked all the pole angles/level and that was ok. My polar mount is set to the correct elevation of 38.8°
Satellite elevation is 31.6° + 6.7° (magnetic declaration angle) = 38.3°
So in the end I started to play with the lnb position and have found the the boom arm is about 5mm to long!
Has anyone else ever come across this? Or am I barking up the wrong tree?
