dish skew

[roche]

i want to get 123 deg to right looking from behind. What will the pointer in elliptical 18 by 24 read?

If you're talking about galaxy at 123W you will need a linear lnb and probably a bigger dish depending where you live.

no, i'm pointing to ciel-119-110

90 degrees equals no skew, (LNB level with the horizon) 123 degrees would equal a +33 degree skew clock wise (from 90) looking from the back of the dish..

Here is a site that will give you a visual indication on the skew needed at your location.

so if the scale from left to right starts at 40 deg, skewing clockwise the pointer should stop at 57 deg???

[Terryl]

If 40 degrees is equal to the LNB level with the ground _____-_____ then you add +33 to it rotating the dish clockwise from the backfor a total of 73 degrees.

This may help.
