I have a triple sat dish to receive tv channels broadcasted through three satellites. .
It is a very convenient dish, it is small making it easier to install out of sight and allows us to watch a interesting wide variety of channels. Ranging from Thailand to Latin America. The disadvantage of such a dish is that directing it towards the satellites requires quite some precision. When the ideal direction is found it always is a tedious task to tie the bolts in such a way that the dish doesn't move. 1 mm off and you don't have reception. A tuning process that also needs to be repeated after storms or a change of season.
I am just wondering if there is tightening mechanism that would allow precise directing while not needing tightening the bolts afterwards. Something like a winch that remains stable on every given position.
