Piccies look fine! Better than I can do with camera
phone (cheap one)!

The angle of the rotor arm on which the dish is secured
looks fairly normal: To check, (if it's necessary):

1. The mount...

That the vertical part of the mount, that's the
bent-up bit onto which the motor and motor chassis
is bolted, is absolutely perpendicular. )

If it's not then, as said previously, you will have
all sorts of probs.


2. The motor's chassis/steel holder...

Check that the angle of this is NOT set to the
inclination angle of the dish.. (this is pressed
into the chassis on the right hand side looking
from the rear).

Check that it is set to your latitude at just about
54N. On my similar motor chassis, the latitude markings
are pressed into the metal on the left hand side of the
motor's mount, looking from the rear.

ie.. the side of the motor that my piccie magnifier
(old eyeballs) ) you have in piccies 8 and 9 - the
bottom row of your excellent pics.

If your installer has bolted the dish inclination on
the motor's chassis rather than your latitude, then
I suppose the rotor arm could be quite a bit out, as
it swings from horizon to horizon. On the other hand,
you are getting some things - so I guess it's OK!

Difficult to tell, but it looks about right!


3. Set the dish inclination, if possible, by it's own
protractor - usually pressed in somewhere close to the
dish itself. My piccie magnifier seems shows this as
the curved slot on the bolt just next to the dish itself.

However...

The dish does seem correctly mounted, or at least pointing
almost horizontally - which, for an offset dish at our
latitudes is correct. (The dish only points vertically
into the sky at or near the equator).


4. True South...

Remember that the dish, the rotor arm and the motor are
only lined up together when the whole assembly is pointing
to True South.

Once the motor has moved the dish to a satellite position,
then not only will the dish swivel, but the angle of the
rotor arm will make it seem to twist - almost onto it's
side at the far edges. This is quite normal. It is this
twist that automatically gives your LNB it's skew angles.


So, possibly it is indeed the box and not necessarily the installer,
but I guess your knowledgeable helper arriving on Thursday can also
have a quick check of these things for you.

Pat ..as I said, don't get too disheartened ..keep laughing! We've
all been here ..and cryed buckets into the bargain, (and I'll bet Walt
has as well!) - and in my case also scared the local moggies with a
stream of expletives...!
