One of strangest and perhaps most interesting things I have observed so far through SOTA is the variability of low angle take off performance from summits. It seems entirely repeatable too.
I think it is mostly determined by how good the soil-to-rock ratio is, and maybe how wet the ground is too. But interestingly the summit height, or proximity to the sea doesn’t seem to have a great influence to how well a station performs up there.
Just interested to hear other peoples views and experiences on this. Undoubtedly it’s been covered before I suspect.
