H2H DiseQc motor in opposite way (look pics inside)

[enb141]

Hi guys I got an 1.2M dish SVEC which looks like this

If you look if I want to add a Diseqc H2H motor must be one in this position (looking Upwards)

So now my question is if can I use an H2H motor in the opposite way like this one?

 

[Mr Tony]

unless you jimmy rig the bracket on the back of the dish no you can't

But many folks have jimmy rigged larger dishes with oddball brackets to work with down facing motors

 

[enb141]

It has but instead of using two will only be able to use one look

You'd have to be concerned about the weight of the dish and mount also. Those "2100" type motors might not be strong enough to withstand the dish and the wind loading too. Check the motor's specifications on maximum weight.

Actually I was thinking in this one

Good choice in motors.

There have been lots of threads describing imaginative ways to bolt a dish to a motor.
A picture is worth 1000 words, of course.

Below are a few threads with valuable pictures.
Some are quite long, so just scroll through at first, viewing the photos.
If you're not satisfied or convinced, I'm sure there are many more threads to be found.

Not what I was looking for, but still quite helpful:

enb I have that motor, in use, for a .90channel master/primestar dish. I can't find my manual with the specs in it, but I would say if any motor of that type could handle a 1.2-it would be that one! Its very well constructed and seems to be quite strong.

Hey thanks for those links, I'll post what I did to my dish after I got my motor

 

[Anole]

What I didn't find, but wanted to have you think about was a picture where someone had taken part of a mount off a small pay-satellite dish.
I think they bolted it inverted on their 1.2m dish.
The original adjustment range the mount had, allowed it to be set appropriately.

Probably a DirecTV or DishNetwork dish around 20 inches or so.
I know you don't have those in your country, but you probably have something similar that people discard to the trash, when they discontinue service.

What if you removed the 4 bolts on your mount on flipped it?
You would have to use a threaded rod as an extension to push the elevation up (as opposed to pulling it back)
Not sure if there would be enough clearance for the motor though. ...just a thought

Enb,

Won't the motor action pan the dish in wrong direction (east = west and west = east)?

If it works, that's an excellent idea. Attached is a very badly photoshopped image to illustrate.

Even if this was so, couldn't you change the polarity on the latitude? Let's say the OP was at 15ºN, couldn't they set their receiver to 15ºS? (for the example of flipping their motor upside down)

That might do the trick - change N. lat to S. lat. Quick way to find out, try it with a normal motor setup and see if the motor turns the dish towards the opposite direction.

So what you say is that I should put the DISH in opposite way, hmm that could work too, now another question how the LNB should be?

In opposite way or in normal way?

Enb,

No, don't install the dish physically in the opposite way, just change your latitude from xy.z North to xy.z South in the USALS setup. You will probably have to do this regardless of whether you use USALS or DiSEqC motor positioning.

I believe that otherwise, installing a tube-down motor with the tube facing up will result in the motor turning the dish to the right when it should be turning to the left. The motor itself is still driving the same direction as always, but since it is inverted, the result will be reverse.

EDIT: Enb, pardon me please. I wasn't sure of what you were referring to when you stated opposite vs normal. Read on and I think it gets clarified.

No. The mounting on the back of the dish looks like it attaches with four bolts. When you put the dish together, you could try assembling the mounting on the back of the dish in the opposite way.

EDIT: I fear my ugly drawing caused confusion. Attached is another drawing...

Guapoharry,

I guess I didn't quite catch what you were referring to at first either.
The pictures make the idea much clearer - just flip the dish reflector upside-down on its mount and invert the mount. Then there is no need to invert the motor. As long as there is plenty of clearance, as you say, for the dish and motor to rotate without interference from any of the brackets/hardware.

This can be accomplished if the bolt pattern is symmetrical.

This would probably be the better approach as inverting a downward facing motor would also place the RF connectors and motor control buttons facing upwards and that would allow for rain to seep in more easily, so not the best idea.

Ha Ha LOL!!

I did one too, but didn't post it!

Putney mentioned it first. I can take credit for understanding this and following the words to illustrate.

It helps when you had the same problem like I did....

Another problem could be a balance issue. I would bet that with an inverted motor and the standard mounting that it would be very top heavy. Such an arrangement would over load the motor at latitudes farther away from the True South

Ha Ha LOL!!

I did one too, but didn't post it!

You get credit for the idea. I get credit for the ugliest picture.

Thanks guys for your ideas, as soon as I got my motor I'll post the final pictures about what I did to make it to work
