> you will need some modification in the system to obtain more
> accuracy for pointing your dish-antenna to the bird.
> At normal stabdard, you will have to allow 2-3degree torelance,
> but on C, K-band, you will be required to stay 1- 1.5 degree torelance, 
> max.
> It is still possible to obtain those accuracy using Yaesu, CD rotator but 
> you will have to add some extra circuit and some counter-weight to 
> compensate the back-lash of rotator it self.
