Yep – I did it as I didnt want the dish on the house so needed an unusual install. I guess I could have paid someone for it but I like the challenge.
If you’re ok at diy you should be fine. Routing the cable was the hardest bit for me. I’m borderline zone 2 / 3 so went for the larger size dish. Get some self amalgamating tape too (for the connectors).
I did use a website that uses google sat images to show you what direction to point the dish (for me a neighbours greenhouse). I then used that finder thing (screwfix have them and the kits too). Fiddling / pointing took about 30 mins. When connected to the freesat box some additional tweaking was required but all good.
