Just Sharing This Eutelsat Skew Offset

[s-band]

There have been a few discussions about skew. I'm not sure how widely it's known but most Eutelsats have a clockwise skew offset of 3.535 degrees. This document has a list in Annex 1 and some heavy maths to explain it.

3 degrees is enough to cause a significant reduction in SNR if there is a co-channel transponder on the opposite polarisation.

when i setup on 1w - i always adjust skew to peak signal - as it makes a MASSIVE difference, who knows what impact that make on other sats, but seems ok to me.

Not using a universal LNB also has benefits.

Yes, I have heard good things about the use of OMT's with a pair of single probe LNB's for C-Band and Ku-Band from forum member "scopus".

Yes, I have two SMW single probe LNBs with OMT on my Precision 1.3 fed into a powered multiswitch which gives excellent results..
