Well got hold of a type 121 KA dish , The dish face is a lot more heavy than the ku equivalent 1.2 , I have temporarily set it up I have taken a spare set of 1.2m ku arms and used them for now as the arms that come with it only allow for a 20mm feed/lnb , set it up and it worked where the ku band version of the dish would not on sarosat , Have tried to upload some photos but the forum says the size is to big
