Bud dish flop?

[SatGuyPR]

NOT my dish! ... but wana be...

Iam looking to do the same thing on my BUD...
but was afraid of the penalty... flopping...
this guy did it... dont now if this is safe...
but there is it...

Look at the steel plate extention on the actuator pivot...
seems to me that it is there as a mechanical advantage...
I prefer it in the horizontal position... but not sure...

Will do this soon... location is Puerto Rico (18N,66W)
My range is 90w-137w with 18in actuator...
will buy a new SuperJack 36V 36in ...
to reach these birds... if posible...

>Hispasat @30w
>PAS1R @45w <--- Puerto Rico locals CBand free-to-air
>PAS9 @58w
>Amazonas @61w

Note that these birds are in my BUD left side...
actuator is mounted in the right... from behind...


Need some help here...
Comments are welcome...


BUD pointing to Hispasat @30w

Same dish... now looking at 61w
since location is at 66w ...
this bird is close to True-South...
dish and base near 90 degrees...

Now we can observe the plate extention
mechanical advantage... just draw a line
between the factory and the ring bolts...

Thanks to July for this photo...

I can't help but think about relocating the positioner to the opposite side of the dish. The assembly directions we used to get 20+ years ago had the east or west coast setups

Of course I would just go ahead and put up a modified dish for far east sats.

Its the "linear east" vs "linear west" idea. I have seen dishes setup both ways.
I use a 36" arm to over extend my polar mount a little but it does not flop. I can get from 40W to 139W. without flopping. (but its close on the east)

I have an spare BUD-10 ... not mounted at this time...
was considering that option... for east sats...
but have some sight problems on low east elevation

Thanks for your feedback...

Your range is 40W-139W ...

Whats your local meridian/longitude ?

From July test on Hispasat 30w...
66w-30w = 36 meridian degrees on flop side

From calculations... 66W horizon is 1W-139W

Have someone ever reach that far ?

Is it save ?

Wind can be an issue...

There is no snow at this location...
but tropical storms during our summer season
from june to september....
I remove the mesh only... when needed

Two additional things I've notice about this geometry is that the pivot point is not centered and the dish is actually offset to the right by appx an additional 1/8th D of the ring. The mechanical advantage is more leverage [less work for the jack] but I would think such a pivot point would impact declination tracking. Perhaps it it located far enough south that declination errors are not much of an issue. The other thing is the absence of a mounting point for the jack for the opposite action. Again likely intentional due to the offset pivot point. Intresting to say the least. As for the "extention", I would think it is more out of necessity in order to fit a longer jack on a system that is designed for a shorter one.
