OK. Well, I have installed this motor and have been playing with it the last few days. Unfortunately I didnt have the type of dish I wanted to use sitting around so I had to improvise, you will see in a few minutes what I/m talking about. Now of course as explained above the SG9120 Heavy Duty comes with a 50mm tube. There are lots of dishes out there that require it. Some dishes you will defenitely not be able to use this motor with unless you do some really serious re-engineering. Just about any dish that uses a "U Bolt" clamping system will work with the hardware sent with the motor. These look like this pic below. The WS9036 90cm and the Hotdish 90 are 2 examples of dishes that mount like this so either will fit this motor.
Now if you have a Dish with a 40 mm round mast mount like these pictures below you wont be able to use this motor:
If you have a Dish with a 50 mm round tube mount like in my pictures here you can still use this motor, however you will probably have to take that 50mm round tube mount bracket all the way off the dish so you can open it up to get it around that lip at the end of the shaft on the motor. See pic one in this post and you will see the lip I'm talking about. Its approximately 65mm in diameter. Again if you have a clamp system like shown in picture 1 you wont have this problem.
I was using a DirecPC fiberglass dish to do my testing. It has the 50mm round tube clamp as you'll see in the pics below. This would also work with a Dish Network SuperDish, buy you'll have to do some modifications. Anyways I chose this old fiberglass dish because it had the 50 mm tube clamp and because its heavy. This old fiberglass dish is much heavier than my 36" dishes i have sitting around here so i wanted to see if the motor would handle it. It did, with no problems at all.
Here is some pics of my fiberglass dish install:
Thats a FSS LNB in that last pic, this dish was once used for satellite internet. Anyways I did replace that LNB and just strapped a cheapo 0.3dB in its place with wire ties for my testing and i was actually able to get decent signal. I programmed in 72.0W, 97.0W, and 123.0W and motored in between them for a couple of days. The Results:
The motor was as accurate as anything else I have used, i had absolutely no problems. I was using DiSEqC 1.2 saved positions. The motor never once failed to find the position, i probably motored between these 3 sats 60-70 times over the course of 2 days. No errors or blinking orange lights at all. It did its job each and every time. The motor was quiet, similar in noise to a SG6000 or a SG2100. It seemed to have no problem with the extra weight of the fiberglass dish I was using. Operation was very smooth. I do not think it moved any faster or slower than other motors I have used in the past.
One thing I found I really liked about this motor was the buttons. I know its a small thing but the button for moving east/west manually and the button for the LED indicator are made of a softer more pliable rubber material than compared to the SG6000 I have here. Its also more of a clear rubber material. I liked this for 2 reasons.
1) It is much easier to see the LED indicator. On the SG6000 the button is not clear, more white than anything and especially in the daylight you have to put your face right on it to see the LED. This is much better on the SG9120 because of the material.
2) Its easier to use the manual east/west button because the rubber is much softer. On the SG6000 sometimes its a real chore to move it manually because the button is "harder" and this makes it harder to push, especially when you have to push twice and hold to go east. The room for your hand is limited in the first place. We've talked about this before here on the forums.
Anyways, thats a small thing, but sometimes small things are important.
Overall I really like this motor. I really cant say anything negative about it at all. I could do without the 65mm lip on the shaft, but thats not really a big deal. It would be nice to have a 40 mm shaft for it if needed, but then again lots of people need 50 mm shafts and on many motors such as the SG2100, or the SG6000, and others you have to pay extra to get a 50mm shaft so its nice to have a motor with a standard 50 mm shaft.
Now, metal verse plastic gears, thats a long term test. I have heard pros and cons of each and honestly I dont have the data to back up claims for either being better so i leave that for you to decide.
I would buy this motor, and because I would use it myself, I will sell this motor and have no problems at all recommending it.
I would now like to thank Robby at WS International for providing this sample to our forum to test and review for our members. Thank you Robby, we appreciate it.
And I would also like to remind everyone here that we will be giving this motor away. Check the contests/giveaways section, there will be an announcement soon.
