It will turn it , but will it keep it there in high winds ?
Thre are many horror stories on here of DiSEqC motors having their teeth stripped in bad weather. So if you are in a semi or exposed location then the normal reccomendation for dishes of 100cm and up is to get a 36v motor to do the job. Comlptely your choice of course but it will probably save you expense and heartache in the long term.
