I don't really have a drawing, but I do have some close up photos. The base for the mount was the bearing from the car wheel. On top came a steel holder for a wooden pillars, and on it I put some other regular bearings for another axis. There's a cog wheel for future, when I put motors on it.

Alex, great idea regards the loop antenna. I’m gonna make one!
But will make it so that I can use the actual hardware in the system so that I will hopefully know how the system works together and then for bad places, and then I can do to experiment to reduce the RFI.
Sound?

I may have made a big mistake. I didn't integrate the signal at all. I just turned on SDR sharp and looked at the signal and expected to see it there...

Simply covering the feedhorn with aluminium foil or suitable metallic lid, should make the peak disappear. This can be a confirmatory test.
