I currently have a 80cm dish with a dual lnb with which I currently receive hotbird and astra 19.2. I would also like to receive canal digital on thor 1.0 w. What I am wondering is, would it be possible to add an additional lnb to my existing set-up to receive signals from this satellite, or would my only option be to upgrade to a motorised set-up? Any help would be appreciated, thank you.
