Here is a picture of my standard 50mm L-bracket that I use for most of my fixed installs. My guess is it could support that dish pretty easily.

It's a proper Hobby Horse... no pedals.Did you have to include your installation vehicle in the photo as well??
My first 80cm dish in 1991 came with a mount just like that and it's still in use today, but it's now painted white to match the walls.
