West side no problem as last sat is 30 w then neighbours wall blocking line of sight though dish can go further maybe till 40w
But if I lower the dish on stub I failed to find arc.
Any method of getting arc if I lower the dish on stub.
TBH, if I understand the geometry correctly, if you move the dish further down the stub then you will have to "start from square one from on Thor" and tweak the declination setting. of the dish (but I could be totally wrong on that! :()

But then dish have to go bit west to correct the arc. And problem remain the same
Motor still stop at 51 east
Correct, but it wont touch the wall when you move the western endswitch

Moving down the dish on the motorstub wont change the arc !!

qv my preceding Post. Position on the stub is irrelevant.

When I started I mounted the dish on stub about 1 inch higher
That time I got everything apart from
42 and 52
Well (and "assuming" the rest of the setup was correct - I'm not totally convinced on that point! - ??) then @Gladstones55's post above does raise the question of could there be reasons why @Trust & @Lazarus's posts might not actually be "correct"???? :confused

If grip of the dish on the motor stub is irrelevant
And I lower the dish 1 inch
Will I loose the arc or it’s stay on the arc.

I am not proving anybody wrong
Cause I am a learner
But that was my experience

Laminas 1.2M fibre dish with an IBU, on a Clarke Tech USALS motor, covering 57E - 24.5W to an Octagon SX88. Displayed on a 20" Dyon LED TV.

Seperate 80 cm dish on 28E with a Humax Freesat for SWMBO.

Moving the dish down the motor stub won't effect the arc or the dish elevation. After all you are aiming at a satellite over 35,000km away so a few centimetres down here on earth won't make a difference. Make sure the dish is still exactly aligned with the centre line of the motor stub.

@sonnetpete also says the same. Because it's absolutely correct.

If you slacken the clamps to make the change under discussion, I very much doubt that when re-securing those clamps the dish will have maintained exactly its former rotational position with respect to the datum mark.

Then there's the by no mean uncommon issue of the dish skewing a little out of kilter depending upon how the clamps are tighten and where they happen to bite.

Ok thank you all
I won’t touch the limiters instead move the dish down a bit to get to 52-53 east
Will report back

If the limit is by the limitswitch at 52º , you wont get to 53º without moving that switch

Will take it off and have a look where the Limit is set
according to ozumo it’s set at 60

No my limit was originally set around 52e as well, after I moved the limiter it was USALS that wouldn't send it past 60e :)

Still ok to use DiSEqC 1.2 to get pass 52e

Are you happy and keeping it or it’s going back ?
If going back what else you are considering to buy

Yes keeping it. You can use diseqc 1.2 if you want but I'd use USALS, as it should point exactly where the sat is from your location. You won't get to 53e without moving the limiter.

Frankly, with a 75cm dish, I doubt there would be that much difference because of the "beam width" (at the detriment of "gain"!) of that size of dish as compared with a slightly larger one - when set on the middle between 52E and 53E (i.e. 52.5E) you'll get a lot of channels on the former and (very definitely and depending on the weather!) maybe one or two on the latter and there would be very little improvement (if any??) if you actually pointed the dish directly at 53E.

If the dish won't go past 52e with usals how do we even know if it's getting to 52e in the first place and not stopping slightly short? I admit I've never used these new fangled diseqc motors before, so can't be sure, but I'd want the usals to at least go to 54 or 55 just so I could know for definite that it's actually capable of getting to 52e.

I would use Dishpointer to check the line of sight before moving anything. I can get 52°east 12302 V 27500 Türkmenistan Sport. Snr: 91%. Agc: 73% on a 90cm Fibo with no obstructions.
