Problems Locking 55,5W° Intelsat 805 in Portugal (C Band)

Maybe somebody could help mrhardylima , he trys to lock 55w Intelsat but he can't simply do it at all , all the time he only catches 58w or 40W.

Sometimes he even got signal from 2 Satellites at Once like 40w and 37,5w

He owns a 2 M Dish and is from Lisbon Portugal

my is the elevation or the position of the dish wrong.

here are some pictures of the setup maybe somebody can give a clue how to help.








i will add more pictures soon

the lnb & feedhorn don't look right -

you could measure the focal length & check the f/d ratio to see where it is compared to the focal length & f/d ratio for that dish

do you know the beam width

Check LNB position using this calculation: (D*D)/(16*d) where D is dish diameter and d is dish depth. So, measure dish depth with a virtual line from extreme border and dish center, and then make your calculation. You will obtain exact distance from dish center where LNB must be installed. Make some test moving forward and backward your LNB finding the best position. Good luck.
