I'm just wondering about other posters dishes moving in strong winds.
I am having some issues with my 1m Gibertini and I'm getting fed up of having to realign it manually .
The dish is a 1m Aluminium Gibertini and its attached to a Superjack DG120 motor which is attached to a 2" scaffold pole on a TK bracket.
Its been up for the last 2 years and when it works its great .
It works well for a few months ,until a strong wind blows and I notice a reduced snr on the weaker sats especially 16e.
I readjust the motor position via software and that is fine until some more wind and eventually I need to realign it after 6 months.
The pole is still plumb and the motor declination is still at its starting point.The dish angle is still the same and the dish is still flush on the motor arm.Bolts are tight,no give.
The odd thing is that the dish always shifts Westwards .
When installing the dish I designed its positioning so as it would be sheltered from Westerly and Southerly winds .
I think the motor is shifting westwards on the pole .
The Superjack motor along with the Moteck motor has a poorly designed backplate .The U bolts that are used to attach the motor to the pole are difficult to tighten properly as the bracket metal bends when you tighten it .
The clamps are made from terrible metal.
I put 2 flat steel plates behind the brackets ,it was the only way I could tighten the bracket properly .
I think this flaw is causing the motor to move in a South South easterly wind ,when the dish is looking straight into the wind at 28e ,where it is primarily parked.
I was wondering when other peoples dishes move out of alignment what moves ?
The dish elevation ,the dish on the motor ,or the motor on the pole ?
I'm going to solve this matter ,even if I have to fabricate a reinforced bracket with new clamps as I'm getting fed of realigning the dish.
