WS1247-120cm-1 offset Ku dish

[jibaro29]

Hi guys,

I have a couple of questions concerning this Ku dish. First, Would I be able to get C band using DMX741U lnbf? And,What type of bracket would I need for my SG2100?

Thanks

Does the dish mount look like this?

What is the diameter of the pole?

 

[jibaro29]

Yes it does. Is that going to be a problem?

 

[Mr Tony]

the SG2100 isnt really compatible with a 120cm dish...they claim it but you need a dish that is very very light

A HH120 would probably be able ot motor that dish around and since the HH120 has the shaft up (versus the SG2100 where its down) the dish could probably be left as is with no modifications

 

[jibaro29]

Forgive me for my ignorance but, will a Stab motor work better than the SG2100 on this particular dish?

 

[Mr Tony]

yes (STAB makes the HH120)

 

[Mr Tony]

I assume the pipe for that mast is at least 2 3/8"...maybe bigger

I'm not sure Ice. I already have a pole in place. I have not ordered the dish as of yet. I'm just trying to get some inputs before I purchase this item. Here's the link to what I'm looking at; http://www.galaxy-marketing.com/ws1247-120cm-1_2m-47-inch-offset-ku-band-satellite-dish-for-fta.htm. My concern is the motor to dish bracket hookup.

 

[Mr Tony]

you would need a heavy duty motor like the HH120 to move that dish then

The outside dimension of the mount is 3 inches and the inside dimension is 2-7/8 inch in diameter.

Iceberg is right. You will need to use the HH120 made by STAB. Besides the fact that the HH120 is a stronger motor, the way the back bracket of the WS1247 1.2m dish is designed, no other motor will work with it except for the HH120.

There are two U-bolts that will tighten around the shaft of the motor. Unlike the SG2100 or SG6000 that are manufactured for dishes "up to 1.2m" but are realy ment to be used on smaller dishes, the HH120 is designed specifically for a 1.2m dish. STAB HH100-HH120

dang thats a big mast...but at least I know what I need if I wanted to get a taller one

I'm curious what the logic is re upward vs downward shaft. Intuitively, it seems to me that a downward facing shaft would have an advantage over an upward facing shaft, because the downward shaft allows for the dishes center of gravity to be closer to the rotation axis, requiring less torque to move it. Plus it seems like the downward shaft would be more water-proof.
Anyway, I've never thought much about it before, so I'm curious what the advantage would be for an upward facing shaft?

It looks like my some what low budget project just got a reality check. I checked on line and the price for Stab 120 goes for around $135.00. " Where is my stimulus package". I sure could use one right about now.

some options:

The less-expensive Sadoun-supplied DG-380 motor will swing a 1.2m dish, but it has a downward-pointing dog-leg shaft.
The STAB HH-120 is the only obvious (H-H) solution for the WSI dish.
Double check that the dish mount will fit the shaft of any motor chosen.

If you look at the Fortec Star 1.2m or the GeoSatPro 1.2m dishes, they'll fit the 380 motor just fine.
Actually, the GeoSat 1.2 mounting bracket allows for top or bottom entry, should it be convenient.
... the Fortec may, as well...?

Just ordered, and received 2 wsi 1.2 meter dishes from galaxy-marketing this last week, and they came in with the best shipping price of $129.00, versus sat av at $215.00, and sadoun at $377.50.
Doing some changes here to the dish farm.

I believe the Fortec 120cm does allow for both top or bottom entry as well. :up

I just got my 120cm dish that you posted above and you most definitely would need a HH120 for a couple reasons

-there is no way a down shaft motor will work due to the oddball bracket for elevation
-this is one heavy mother....and the brackets are very heavy

 

[Sadoun]

Yes, it will work with either styles. I would only recommend the DG380 for this size dish. Faster, Stronger, and More Range than the HH120.

 

[jibaro29]

That is good to know Ice, thanks!!

What is the difference between the Stabb 120 and Dg380 other than the price?

 

[Sadoun]

Both have metal gears and heavy duty mounting brackets.
