Good point, olliec420! There might be another cause!
The 'line-of-sight cause' is till now just an assumption. It's unsure if the app picture gives the right result.
A way to check this, is:
Make a rectangular cardboard with base of 89.2, and hight of 99.0: exactly the values of the line of sight checker of dishpointer (see post #14).
Or multiply or divide these values by any number, to suit the size you want to make. It's the proportion that matters, nothing else.
Than cut the cardboard diagonally, from corner to corner. Then you get the exact elevation angle to your wanted satellite.
From your dish location, hold the cardboard in the direction of the satellite, with the base exactly horizontal (use spirit level or something).
Then look along the diagonal line. Do you see a tree there, or do you look above the trees?
That way, you can test if line of sight really could be an issue here.
There are, of course, other ways to test line of sight.
E.g. how high the shadow/sun transition is on a vertical stick at the dish location, at the time the sun has the same azimuth as the satellite. But some calculations are needed there (I use
Satellite Look Angle Calculator ), and you need to knowthe exact distance to the 'obstacle'......
