Diseqc motor - can it be fixed upside down

Question has been asked before but wondering what people think now. The idea would be to mount the motor on the mast such that the small stub pole from the motor would point upwards instead of pointing down.

As far as I can find all the popular Diseqc motors available now have the stub pole pointing down. But I thought some early Diseqc motors had the stub pole pointing upwards - are these motors still obtainable now.
 
Yes they can be mounted up side down but it would increase the chance of water intrusion into the gears and coax connections.(not a good idea)

Also the East/West motion controls would be reversed.
 
They can be mounted upside down, but surely the curvature of the arc would be reversed.

Correct your reference satellite would be the only satellite you would receive then the dish will go up instead of down to east & west :-rofl2
 
W-1 - that's absolutely true because what else could it ever do (basic engineering!)?
 
It's more complicated than that.

If you mount a standard diseqc motor upside down and crank back the adjustment so that the stub pole is angled at the same angle as a stab type diseqc motor then it would track the arc in the same way as the stab type motor.

But would there be enough adjustment room on a typical diseqc mount? I suspect not. In UK I'm sure there would be no chance. I might have a slim chance because the dish would be at 44°N, and would not have to be cranked so far back, but I must be at the very limit.

However, there remains the problem of the LNB plugs facing upwards and open to rain, and presumably other features (drain plugs, mechanical components?) that would not like to be the wrong way round.

The simple answer is to buy the stab motor, but an interesting technical discussion.
