If you look at the full spectrum at 28E on an analyser and gently pull
at the rim of the dish you can see some signals strengthen whilst others
weaken.

Right. I'd guess a spectrum analyser would be a bit of a luxury for me,
though. ;-)

I did quite a bit of Googling on setting up a motorised dish. Most of the
Utube stuff just confused me, as I simply wanted an idiots guide.

So here's mine:-

Make sure the mounting pole is truly vertical. That could be tricky
working off a ladder.

Set the motor to 0. Mount the disc making sure it is pointing straight
ahead, relative to that 0. Some dishes may not have a big enough flat on
the back to use a set square, so measure from each side of the dish to the
motor centre. Make sure the dish mounting is the correct distance up the
motor mounting tube.

Set the elevation on the motor adjustment, using the motor maker's data.
And then the disc bracket angle.

Now rotate the motor mounting to point due south. I found a phone app
better than a compass.

My receiver then found all the satellites in its list - with the exception
of a couple to the west where my dish is looking through a thick large
chestnut tree.
