Good morning I am going to move the mounting down the motor pole today
Good morning I have moved the dish bracket down the motor pole so that there is more room to adjust the elevation.
Have adjusted the elevation but no improvement in signal.
So will be moving it back up as there is less leverage on the motor if the dish is wind blown with the bracket higher up. Kind View attachment 79488 Regards Spiff
Good morning from a wet and windy Mullion Cove
An update on the 1.3m dish from SSS. After many emails they realised that the image on their website is not of the dish they are now selling.
I had to persistently repeat my question regarding the steel bracket not fitting and bending the Ally dish, as it appeared to be side stepped in each reply.
My last email to SSS below and their reply.
Good morning Dave another sunny day : )
I am sure you know all this.
As the frequency's received have wavelengths in the order of 10mm the surface should be accurate to 1mm at least to perform well.
The curvature of the dish is greatest near the vertex so it changes over the surface area.
If the bracket was shaped to fit at one point, then the manufacturer moved it up or down the back of the dish for whatever reason, the dish is going to have to bend to make it fit.
My bracket did not fit by a mile, I should have stopped at that point.
If you find all the brackets do not fit the rear of the dish shape, just send us another dish that has not been fitted to a bracket.
I will then bend our bracket to shape before refitting it.
As it is, the ally dish I have is not going to spring back into shape.
It does not perform as well as the Triax with the same dual output LNB, though as I said before when fitting a mono output LNB it performed about the same as the 1.1 m Triax.
Good luck with the new shelving, we run two online businesses ourselves and have to maintain our rental let, so I know what it is like to have a lot to do : )
Kind Regards Allen
The reply from SSS : -
Hi Allen,
Put together a dish for assessment on Saturday.
The back plate is curved but the dish is curved in two planes (3D) and so it would be difficult for the manufacturer to exactly follow the contours of the dish.
I think the problem you have is due to over tightening the bolts which hold the back plate to the dish.
This is not needed as they are not standard nuts, they are Nyloc nuts so they will not come off if the tightening is not too great.
They do not need to be any more tight than to stop rattling between the back plate and the dish.
I guess you could put some rubber washers between the back plate and the dish to prevent over tightening and make the tightness slight but not rattling
Or a bit of rubber or weather strip between the flange of the backplate and the dish.
I have some 1.0mm (approx) rubber sheet and could send you some if you need any.
This will just allow tightening to occur to the right level without pulling on the dish.
But yes that is how the dish and back plate have been manufactured.
My previous email about clearance holes of + 1.0mm in the backplane is also worthwhile.
thanks
Dave
End of email from SSS
This part about clearance holes I cannot find in his previous emails, not sure what that is about : )
I would also add that the dish fixing bolts are coach bolts the type with a square under the head, the holes in the dish had not been shaped to fit and were round consequently the bolts had to be tightened to pull the square into the hole.
They are not Nyloc as he said, not that it makes any difference.
The bolt holes for the LNB steady are the same and very ragged as if the drill has been put in on several angles to thin the edges of the hole so that the square of the coach bolt could dig in
In all very poor quality and inferior results to the Triax 1.1
I am 70 this year and have been left with an erratic heart beat with all this, I shall not now be going to spending close to a £1000 on a larger still dish with polar mount, well not with them anyway.
So if you buy a bent dish mount it on rubber, honestly what can I say to that : )
After sales is everything, I run two online businesses, the customers are people just like us and should be treated with care and consideration.
Thank you all again God Bless Allen
