A professional TV mast rigger did the job.
I had a look at it again... and I'd say it is more like 3 meters up from
the chimney, but it is still 4 m up from the roof at the chimney so it
is a bit hard to get to.
Anyway, the repositioned antenna now makes the borrowed Ashtech Z-12
lock up at L1 and L2 for sufficient amount of sats, but the S/N is
lowish, which I think I will blame on my RG-58, not too professionally
done coax work... could TDR it thought. Hmm... why didn't I think of that?
