Usals problem & alignment

[TJExcalibur]

If the pole is perfectly upright and the Latitude and Longitude settings are correct it will work perfect. The only other things to adjust is the tilt on the dish.

Here I disagree , the motor is turning to ± 1.3º EAST on the scale ( 2.1 minus 0.8 = 1.3)

Wouldnt using 3 west mean the motor is pointing due south rather than using 0.8 west?

 

[Trust]

If you send the motor to 3º W the pointer will show ± 0.9º West

It doesn't matter which satellite the dish is pointing at 0, on the motor scale, should always be pointing to your true south, your longitude position, in this case 2.1W.
You are correct that the motor will have turned 1.3 degrees East, from 2.1W, to 0.8W, but 0 should still be pointing to 2.1W, that's 2.1 degrees West of south.

Your'e right , I misunderstood what you were writing .
You were talking about the zero mark on the scale . I thought the pointer at the shaft .
Sorry !

Used a digital spirit level to see how level pole and brackets are, the pole is 0.17 degrees off east/west. Also 0.17 off north/south. What seems to be the issue is the dish bracket on motor pole is 1.22 degrees off, could this amount cause tracking issues? I also checked level on top of motor pole, which is 0.87 degrees off. Back of dish looks like is 0.17 degrees off. See photos attached. Do all those values need to be 0.0 to track sat arc?

The photos were taken when motor at 0 position.

Your thoughts?

The pole needs to 100% accurate and until then the rest of your readings will not be correct.

I think the 0.17 degree slant on the ground mount isn't as much of a concern as the far greater error on the Stab rotor pole.

Can you see where the changes are, at the gearbox end (where its clamped to the mount), or tolerance at the front end ?

Either way there is something not right with it.

Is it possible to introduce the error on the Stab rotor pole mount by the way the motor bolts are tightened on the pole?? Same as with dish mount on the motor pole (1.22 degrees off)

I think Stab motors are rubbish, get a Technomate 2600,

Send the motor back, its crap as you should not have to mess about like that. Get a TM 2600 Mk3 from World of Satellite.

I would have but worry about losing 50cm from line of sight. How much lower would this motor make the base of the dish compared with Stab usals? At the mo the base of dish is approx 1.65m high.

 

[TJExcalibur]

Without seeing a photo of you setup its hard to know. I fitted a long pole to my 2 wall brackets enabling me to move the setup the length of the pole, plus the pole rests on the flat roof for extra support. Can't you fit a longer pole?

See post #17 on page 1. I have also installed 3 way guy wire on the install which was after i took the photo. I think if i go any lower then base of dish might be just below neighbors fence. I dont want to fit longer pole as that might have issues with high wind.

 

[Channel Hopper]

It probably around 40cms, less if you are careful with where the dish is clamped on the shaft.



You could also invert the dish on the bracketry reducing the viewing angle issue further.

 

[TJExcalibur]

I think the only long term solution is longer one piece pole, preferred with guide wires and push the extra length into the ground.

ill play around with the Stab motor over the weekend and see if I can improve the setup. If not ill just get the Technomate. Thanks for help.

@TJExcalibur do you find the Technomate easier to setup than the Stab or is it just better built?

 

[Channel Hopper]

The Technomate motor (it is a clone of another brand) is much easier to set up, since it has a manual control near the two connectors.
I have installed about ten in total, and all receivers appear to work well with no requirement to erase/reset/recalculate values when upgrading either dish surfaces, or receivers in the home.

Additionally the TM model moves quite a bit faster across the arc than other motors, the Stab being about the slowest I have encountered.

Thanks for the explanation. Is the motor quieter than Stab? Are the brackets behind motor similar to Stab?

I found it easy with the TM 2600. The Stab went at a different speed depending on direction it was moving, would not go back to zero and the seller refused a refund when it stopped completely. Contacted Stab direct but they were useless.

Not as quiet as the one TJ had

The brackets are similar , but thinner material, they cannot be swopped over though as the hole distances are different.
