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.

Reply 3 – Sep 11 that Notify me of follow-up comments by email. It must be set within certain limits to reduce the number of errors received on both vertically and Horizontally Polarised Transponders. This method assumes that the dish is a clock.

I assume the rest of these are scrambled or other signals? Mark the positions of the future holes on the wall. Seems to me that the skew of the dish is not the same as the skew angle associated with the LNB, any ideas?

It is also affected by how much the installed dish deviates from the vertical position. Satellite Dish Alignment Tools. As a trained conference speaker, Burns speaks nationally on the art, science and inspiration of freelance writing. If you are told a polarisation sskew need to know if this refers to the uplink or downlink.


The LNB and dish must be perfectly focused on the satellites, and are adjusted by setting the skew, elevation and azimuth of the dish.

Push it forward again and rotate the LNB. Make sure you set the dish correctly to get the maximum signal strengths.

What is LNB Skew?

It’s a real doozy for those in the field presetting the typical pol with no luck tuning off a moderate eirp. If something is at 45 deg it sounds like a circular polarisation system where there is a polariser between the OMT and the horn.

To start discussing the satellites polarisation is confusing.

Leave this field empty. This tutorial is for Ku band frequencies on an Offset dish but the rules can also be useful for C skw as well as Prime focus dishes.

When you hit the highest signal strength, tighten the screws holding the LNB.

How to install and point a satellite dish (DIY)

For the satellite due north the polarisation adjustment amount is zero. To align the polarisation accurately by measurement only, you need to find two severely degradred but exactly equal levels either side of the very broad co-pol maximum. The other image, B shows an LNB pushed all the way soew away from the reflector. Note that the scale readings may start at 0, 90, and go forwards or backwards. If you are in the southern hemisphere and facing north east then you need to turn the feed by an amount clockwise, as viewed while standing behind the dish and facing forwards towards the satellite in the sky.


Its also been pointed out that the prodelin waveguide has a notch machined into the inside of the throat to account for this, although I didn’t get a chance to open it to see. Brought to you by Techwalla.

When anchoring the dish’s mounting pole, make skeew the pole is percent vertical, or perfectly ,nb, not tilted in any direction.

There must be a point where the signal disappears completely even when the dish is correctly aligned at the correct satellite. North can also be called deg.

Meaning of LNB Skew and What is LNB tweaking and how is it done

A skew angle of zero is when the dish longitude and satellite longitude are identical. A tilted mounting pole will affect the dish and LNB skew angle and make it more difficult to finish aligning the dish. Have a spare primestar dish, will try that next in case it is toroidal not being strong enough although Dish is very strong as is T5 and a few other Ku sats.

Make sure that its signal covers your area.


Please, can you help me to get some apps that can secure my files. The earth station cannot be transmitting on both polarisations simultaneously.

Hopefully understanding of our users for the inconvenience caused.
