Had a small glitch yesterday when I found the antenna pointing 90 Degrees off it's intended direction.
Although this is not something you would want to happen, it underlined the robustness of the system because I was still getting a 20 Mbps download speed!
Support service was good with only 2 hours from phone call to the installer returning to refit it.
Hopefully all OK now
although I did go up on the roof with him so I know everything I need to do to align it myself.
