LNBF skew and Elevation in HH motors

I am ne to this. When you install the HH motors on a dish, i know it will rotate to find the Azimuth angel. But, does it also rotate to change the elevation and skew for the LNBF?

Thanks,

the skew of the lnb is changed electriclly, the h-h nows what the skew is needed for each satellite and send the right amount of power to get the right skew. so even the lnb dosen't move , somthing change electriclley inside as if it was moved michaniclly. got it?

:shock: Oh Isee! Thanks for the info!
What about the elevation angel? does it change along with the Azimuth?
Thanks,

No, because if set up correctly you are using a "modified polar mount". The satellites in the sky don't appear as a straight line but as an arc. If you are set up correctly as the dish turns it tracks the arc. Your most south satellite is the highest satellite in the arc. The ones to the E & W are progressively lower in the sky. Also as your dish turns you will notice that the lnbf is also canting and this also adjusts the skew angle. 8)
