LNB SKEW PDF

LNB “skew” angle is the rotational position of an LNB on the dish arm. The actual “skew angle” is dependent on the satellite and on your. Learn the process of Skewing an LNBf correctly. You will need the correct LNB skew in order to receive the maximum signal for your satellite. Mount it all, including the LNB, and screw it on tightly, except the screws that You will need to find out the azimut, elevation and LNB polarization/skew values.

Alternatively send your image to me by email eric satsig. If the dish is correctly aligned at the satellite then the weak transponder frequencies will improve. I am only aware of two satellite systems with polarisations not oriented with regard to the earth’s axis. Now this is how LNB tweaking is done This tutorial is for Ku band frequencies on an Offset dish skwe the basics are the same for C band as well as ,nb focus dishes.

Start with the named nominal polarisation. Both in the Southern Hemi.
