Thanks for the info.
It's not a motorised system.
I ordered this L-type wall mount : https://www.amazon.de/PremiumX-Wandh...076D8Q6YJ?th=1 and it feels VERY light, I'm just not sure about mounting an 85CM dish on it. I need a minimum of 55cm horizontal to align the dish (cannot mount on south-facing wall), and it just seems like lot of weight on the arm of the wall mount.
I might be over thinking it, just seeking opinions about steel vs aluminum L-type wall mounts.
The house is not in a high wind or unsheltered area, dish going on the 1st floor wall.
Thanks
