Official Thread of Free To Air Satellite TV (Part 2)

  I have told you guys that adewest is a trader. he wants money, we dont pay here. and like pitondenz has said nothing you know wey we all conbine no know. so clear from this place, small thieve like you.
gangsta101 i will do as you instructed.
Enitan I beg send this Zain thing to me pls.

Since you have all the necessary equipment, why don't you test it and let the rest us know?

@ Enitan,
pls av gotting the "half baked bread, so let me get the full one" its all about the zain thing
need more details for the pc connection my mail is oyebodewale@yahoo.com

Gangsta101,

thanks for the information
i actually got the etv and all the religious channels. i will try out the bigger dish with the info you gave

@ F_marchal,
that was a nice tip from you, but let me remind you that, obstruction against beams affect more of c-band freqs compared to its ku-band freqs.
Come over to lagos especially lagos mainland, where you will so many DSTV/HITV dishes being faced against Storey buildings.
Many people residing in lagos can testify against that, they know what am talking about.

@ toxnaija,
everything seems to be going on well now, you can give it a try.

@ justx24,
how things for ya end?

@ all,
it seems everyone is satisfied with their nilesat, motorised, w3a, pas 7/10 e.t.c, the much talk about a conference being organised is already fading out.
WHAT ARE YOU ALL SAYING ABOUT THAT?

@ Enitan

 My end is cool , and am getting my acts back together, Wait , are u making any use of my "BUSH INDAPTER"? If not , maybe we organize hw i can get the stuff back , cos one's in a while the CTL stuff comes back on FREE, no rush bro, but maybe before you get out of LAG oo, uppssss   when will that be ? Anyway , its not an urgent matter ooo


 About the meeting , or conference , or get together. It seem its not bound to happen just yet, Hopefully someday , i just hope it will not be After all of us don get mote busy jobs from the senate, ( Abi u no wan be senator?). Anyway , think am done with that issue for now , MASTER TEACH ME MORE OF  FTA KUNGFU.

Anybody watching DAARSAT ?, just want to know if , u know 


Thank you all

About that, beams which are intended for a particular area usually have higher signal strenght, so are more likely to fare better when there is an obstruction along the path of the beam, as long as there is enough signal coming through. dstv, mytv, hitv, e.t.c all have their beams focused on Nigeria, and usually have very high signal strenght, so trees and buildings which are along the beam path in a way that allows some of the signals to filter through (such as in the second picture by F_Marshal), will attenuate the signal strenght, but not so much that they do not allow anything through, but when the signal is weak, like Nilesat for example (a ku-band broadcast) you really need a really good line of sight to the bird, cos obstructions will cost you a lot of signal loss. let me give an analogy, a really bright torchlight will have its beam shine through a card board paper, much better than one whose light is not so bright.
i guess what i am trying to say is that what obstructions do to the reception of signals is a function of the signal strenght (ku band signals are generally meant to have higher signal strenghts to a particular area than C-band), and not broadcast frequency/wavelenght. Infact, i can guarantee you something, you cannot receive even dstv when there is total obstruction to the signal such as in your living room.

@badaru,jujukemist,enitan,twinstaiye,olofofo,captainus and all
Please I need your help. It's a patch for RADIX DT100 decoder, infact it can not open ETV. I have to consult u because my search was futile (I live behind a firewall, thus limiting my search) b'cos I browse with a corporate internet with restrictions. Just drop me a link, can strong patch do the job? can I do data transfer from my strong receiver to the Radix decoder?
Secondly, I have tried to use master code for strong and it never worked (the ones found at flysat) maybe it's just b'cos I don't know how to enter it correctly. I need that for educational purpose only, if you can't answer this publicly pls drop your answer at signalbit@yahoo.com
counting on you.

@ all,
Communication satellite can be likened to a big microwave repeater in the sky. It contains several transponders, each of which listens to some portion of the spectrum, amplifies the incoming signal, and then rebroadcasts it at another frequency to avoid interference with the incoming signal. The downward beams can be broad, covering a substantial of the earth's surface, or narrow, covering an area only hundreds of kilometers in diameter. This mode of operation is known as BENT PIPE.
According to kepler's law, the orbital period of a satellite varies as the radius of the orbit to the 3/2 power. The higher the satellite, the longer the period. Near the surface of the earth, the period is about 90 minutes. Consequently, low-orbit satellites pass out of view fairly quickly, so many of them are needed to provide continous coverage. At an altitude of about 35,800KM, the period is 24 hours. At an altitude of 384,000KM, the period is about one month, as anyone who has observed the moon regularly can testify, mostly astrologers and muhammedans.
A satellite at an altitude of 35,800km in a circular equatorial orbit appear to remain motionless in the sky, is totally false. It rotates round the earth as the earth also revolves along its axis, which results to its days and nights. And thats the reason, if  2 satellites dish facing 36E, is installed at various time in the year, like if one is installed in january, and the other installed around november of the same year.If one takes a closer look to the dish one will notice a slight angular difference.
With current technology, it is unwise to have geostationary satellites spaced much closer than 2 degrees in the 360-degree equatorial plane, to avoid interference. With a spacing of 2 degrees, there can only be 360/2 = 180 of these satellites in the sky at once. However each transponder can use multiple frequencies and polarizations to increase the available bandwidth.
Modern satellites can be quite large, weighing up to 4000kg and consuming several kilowatts of electric power produced by the solar panels. The effects of solar, lunar, and planetary gravity tend to move them away from their assigned orbit slots and orientations, an effect countered by on-board rocket motors. This fine-tuning is called STATION KEEPING. Howver when the fuel for the motors has been exhausted, typically in about 10 years, the satellite drifts and tumbles helplessly, so it has to be turned off. Eventually, the orbit decays and  the satellite reenters the atmosphere and burns up or occasionally crashes to earth.
The highest band is the c-band, these bands are already overcrowded because they are used by the common carriers for terrestial microwave links. The L and S bands were added by international agreement in 2000. Howver, they are narrow and crowded. The next highest band available to commercial telecommunication carriers is the ku (K under) band. This band is not (yet) congested, and at these frequencies, satellites can be spaced as close as 1 degree(e.g nilesat 101, nilesat102/ atlantic bird 4) all at 7W, there are slight difference intheir angle, note that. However, water is an excellent absorber of these short microwaves signals. Fortunately, heavy storms are usually localized, so using several widely separated ground stations instead of just one circumvents the problem but at the price of extra antennaes, extra cables, and extra electronics to enable rapid switching between stations. Bandwidth has also been allocated in the ka (K above) band 20GHz-30GHz for commercial satellite traffic but the eauipment needed to use it is still much expensive. In addition to these commercial bands, many government and military bands also exist on all these satellites but they are kept highly confidential (top secret), thats why they cant be fund on lyngsat, but they exist.  different equipment are needed to intercept these bands

With regard to dishes and obstructions, what F_Marshal posted is correct. Even if you are within the official footprint of a particular satellite and in a strong signal area, your dish and receiver will not receive good enough signal (if any at all) if there is an obstruction in the way such as a house or a tree.

The reason it seems that houses etc in Naija are not obstructing dishes is not simply because of the footprint or strength of incoming signal but rather the angle from which the dish is receiving the signal. For example a dish may seem to be pointing towards a house whereas it is receiving the signal from an angle which is over the house. This is particularly so because the relatively small dishes that we use are offset dishes rather than prime focus dishes. Offset dishes receive the signal at an angle on the face of the dish unlike prime focus dishes.

See an example in the following link:

It seems that the Radix DT 100 is not all that popular; also, it seems that what to do is to convert it to another receiver (e.g. Skycom). If sathob has time , he should google 'radix to skycom' or just the two main words or 'convert radix dt' or something like that.

WRT Radix generally, the best link I found so far is: http://www.sat-television.com/forumdisplay.php?f=660

 

@jujukemist
i live in Kano, Nigeria.

@enitan
could you let me taste the Zain thing? I beg send this to me please, suleayinla@yahoo.com
grateful 2 u.

@Sathob
Please I need your help. It's a patch for RADIX DT100 decoder, infact it can not open ETV. I have to consult u because my search was futile (I live behind a firewall, thus limiting my search)

If your decoder is patched try 9815

@ Enitan2002
On the "LOS" Line of sight issue, I believe Gangsta101 and Enigma may have given you a better understanding of how dishes are angled, but seem to be point in the direction of an obstruction. I hope you've learned one or two things from their explanations.

@ the RED Highlighted
Abeg Enitan2002, mek u tek time type my username "F_Marshal" for this forum correct nah!! De ting no hard to write nah?  ???U don see as other members are beginning to write F_Marshal wrong? 

@ fasone:
I'm glad we're able to help you and thanks!!!!
