A question; how is a rotatable lnb made for the skew with a servo motor and a plastic gear.
I see a lot of videos with rotatable lnb's for the skew.


Best regards
 
example ;
where can the sprockets be bought and how are the sprockets attached to the feedhorn.
with glue or something!?

... told you before-don't call me Shirley :p
Right then, to get started we need a little bit more info from your end MrDish1 to enable more accurate feedback advice
What style, O/S or PF, and size of dish were you thinking of putting a rotating lnb onto.
For which reception band, ie: Ka, Ku, Cband or other.
For home brew polorisers / skew devices etc to perform to acceptable levels require the use of some fabrication skills and a suitable work place and equipment to enable a quality finished home brew product - sometimes it can take many attempts to make something, usually the same object, before you get it right so patience is a virtue.
Source of cogs etc can be a pain to get sometimes, 95% of my stuff i use comes from China.
If you can post decent resolution pictures of your dish or any motorised skew devices you have been looking at and want to replicate will help a great deal.
Good luck with it all - go for it
 
Maybe looking at Rc.
there they work a lot with servos and gears.
Have already contacted Trust regarding Av-Comm

Glue some toothed belt around the lnb then use another piece to drive it.
