African Satellite World and Sat Gear


Ilish,
I have some questions here: Firstly, what dish size are you using with the H-H motor? What is the maximum weight the motor can move comfortably without breaking? Some of us would like to experiment with even a 165Cm offset dish

Technically, the H-H motor should work best for satellite-hunters located north or south of the equator; in other words, north or south of the Clarke Belt (satellite Arc).

I guess, for some of us who are located too close to the equator, fixing the H-H motor cold pose a challenge since for us to track the Clarke Belt, our offset dishes should move either ‘upwards’ or ‘downwards’ and not ‘sideways’ as in the case for guys in the north or south.

Over to you experts; I guess that around the equator, we might have to settle for an ‘actuator’/motor and ‘positioner’/servo control (popular with C-Band / prime-focus dishes).

Check the following comprehensive guide (with video tutorials) on how to fix an H-H motor in north America (north of equator): How to install an HH Mount DiSEqC USALS Motor? Applies to DG280, DG280B, DG380, STAB HH100, HH120, Moteck SG2100

Great discussion. I tend to agree with FTA Nash that it may well be difficult to get good results with an HH motor living on the equator, as in Nairobi. I have installed an HH motor in Europe, very easy, works very well once properly aligned, and yes, it is great and you can get lots of sats very easily. You just change channels from the regular Set Top Box and remote control and the dish moves to the new satellite, amazing. I do actually have an older HH motor here in Nairobi, and have played around with it in the past, but I could really not work out how I could install it, for precisely the reasons that Nash has identified.
 

Hi techdee, can you please share images of your setup. I would love to try it out.
 

Basically, it can carry up to 120cm (135cm) dish.That's the maximum.

In regards to the clarks belt and proximity to the equator, that I can't tell.However, giving it a try can't be all that a bad idea.
 

I tried a brand new one with 135cm dish and it could not stand the weight. the specs indicate that it can move such a dish but practically it cant unless may be you are in the polar regions. It still lies idle in my store room. I believe its perfect with 90cm and below. 120cm and above, it will be a gabble with your money.
 
QIMEU

just work on the right specification with the motor manual.It can lift that 1.35m dish

Did you know that in truth what we call as 1.35m is in fact 1.20m.How do you measure the dish size?

Surely there must be someone who has this stb and is on Eutelsat 7 east.
Kindly please let us know so that we can also join you to enjoy.

Good Afternoon yako2,

Digit**K package on Eutelsat 7 East A working on Srt 4950 H.

Use patch firmware from V2.59P or the current firmware (V2.73P) posted on Crosat Sat Upload Center | Humax | Strong | Dreambox | Tv Channels | Sky Star 2 | Biss | Keys

Snap shots of some of the channels open via patch using Srt 4950H>>>





















Happy viewing:yo:
 
Any one in Kampala receiving Digit**k?
Do I stand any chance of receiving it with a 6ft prime focus dish. Which is the best frequency to track with? Thanks.
 

My opinion: The dish weighs the same whether at the poles or at the equator, hence a dish that can be lifted by a motor at the poles should also be lifted at the equater.

My setup (in Zambia) uses an HH motor and a 135cm dish. I have used the motor for about a year. Its fast flawless and accurate. The motor has a "dont open" seal on it and I have found that when that seal is removed it reveals three screws which you can tighten or loosen. When adjusted the screws reduce/increase the stiffness of the "gearbox" in the motor. When tightened too much the dish will seem too heavy and move too slowly and the motor can get jammed at one position. When screws are too loosened the dish can seem too light and can move too quickly and over shoot sat positions. The trick is to adjust the screws such that the dish can move freely without jamming but at the same time it should be stiff enough to stop where the stb wants it to stop.

Theory: If your HH motor couldnt lift a 1.35cm dish probably the factory setting of the screws was too tight.
Disclaimer: Do this at your own risk. Donations of impossible to use brand new HH motors are welcome.:smiling:
 

I don't see how it shouldn't work near the equator. The trick is to get the motor axis parallel to the polar axis which in our case is nearly horizontal. If the slot provided is not sufficient you can always lean back the pole. My thinking. I haven't tried cause it wouldn't work for multiroom installation.
 


Thanks for the info. It looks like the last motor might just be able to haul my 120cm fibre glass dish. The type used for satellite internet. But i will have to re-engineer the mount. Not a mean feat. I will post a picha of my mount etc kesho. Will COFEK bite Kenya Parafin Lamps & Candles on my behalf when they fry my motor? :A S 39:

We measure the dish along the longer side of the oval. Most of us. But the answer to the dish measurement is a complex one. I will copy-paste a brief explanation/excerpt from another forum.

If you want simple, you asked the wrong question.
My 1.0M dish is 41 1/2" from top to bottom, and 38 1/2 " from side to side.
My 1.2M dish is 51 1/2" from top to bottom and 47" from side to side.

Measuring your dish will tell you what Class ( 90cm, 1.0M , 1.2M ) that it belongs to , but since not all 1.2M dishes have the same effective aperture and focus, and they don't all have the same gain, they don't perform equally.
Dish depth is another factor, because it is one factor establishing the f/d ratio . Matching the f/d ratio of your dish with the appropriate lnbf will give better results than a mis-matched pair.
Simple you are not going to get .

Does this sound like something Confucius said?:biggrin1:
 


I would like donations of power-zapped stb's, especially if they are the SRT 49xx series:evil:
 


That leaning of the pole is what i was thinking, if the issue is as i imagine. I would beat the living daylights out of it if i had it and it didn't work.:A S angry:

my setup consists of a 65cm dish pointed at 17E and an LNB hanged on top which recieves 7E and 5E, inspired by highlands patron. If you go back a few threads you will see his picture. All 3 sats with very good signal qualities. Before this I received 5E fixed on an Lnb arm with dish pointed at 7W, but it had very low signal strenghths and bad quality.

Mr. emboko take one for the team and buy the 4950M 😉

I am gonna do it. Soon as the Mombasa supplier's stuff verdict comes in:A S wink:. But i am seriously considering getting both the 4950 and 4950M. If only the nairobery suppliers put something on "special offer". I would go get those two.

Remember to keep the pole, motor axis and polar axis in the same plane. Small matter.
