Some couple of weeks back, i posted an article on various sate names, positions, frequencies and dish sizes. You can get the article here. But it gets somehow confusing when we mention various sizes of dish, it some times get confusing. Well what i will say is that the least size of dish ranges from centimeters to meters. I will be displaying pictures of the most popular satellite antenna / dish used in tracking satellite signals in Africa.
The standard measurement of a dish size is in centimeters or meters. A centimeter (CM) is a unit of length equal to 0.01 of a meter while A meter (M) is a unit of measurement equal to 100 centimeters.
I will now take them one after the other, starting from the largest(in terms of usability) to the least.. If am still reemphasizing it that am not displaying all the available satellite dishes, i am only uploading pictures of the ones that are useful for Africans in other to watch satellite television.
1. 4.**** Meter Dish(Size ranges from 4.0meters to 4.6meters
The above dish (I mean 4.0meter to 4.5Meter dish) is used to track the most difficult satellite to track in Africa. Most especially, Nilesat and hotbird. Nilesat is an arabic premium satellite company. In nothern Nigeria you can get a handful of nilsat channels with a 1.0meter dish, this is not possible in southern Nigeria. With a 1meter dish, you wont receive any channels on nilesat 7.0W in the south. But if you have a 4.0meter dish or bigger, no matter where you are across africa, you will be able to easily get nilesat and hotbird packages in optimum quantity. Hotbird is on 13.0E
2. 3.*** Meter dish (That is Dish size ranging between 3.0meters to 3.6meters)
The only difference is that, if you use 3meter dish in the south, you will receive many channels on hotbird, but you will hardly be able to receive all channels on nilesat in most part of the southern Nigeria. In fact you may not receive all the bein sports HD channels. However, 3meters dish is a good starter for hotbird and nilesat.
3. 1 meter Dish( That is 1meter to 1.8meter)
1 meter dish is the overall most popular dish after the normal 90cm dish. when i talk of 1 meter dish, i am talking about dishes that ranges from 1.0meters to 1.8meters. It is also worthy of note that, we also have 2.0 to 2.8meter dish. W meter dish is effectively used to get nilesat channels in northern Nigeria, but you cannot get hotbird with any dish lesser than 3meters. Even when you get some channels on nilesat, using 1meter dish, you will get very few(usually bein sports 1 – 5 then where as beinsports actually ranging from 1 – 12). Like I said earlier, you can’t get hotbird signal with 1 meter dish
4. 90CM dish(Popularly know as Dstv Dish)
Another name given to dish type of dish is dstv dish. The reason we have this name for it is that, the is the size of dish that comes with dstv decoders. This dish cannot track nilesat and hotbird. How ever it can track several other satellite channels obtainable in africa e.g, eutelsat 7.0e(known as malagasy), eutelsat 36.0E(known as dstv), Amos 5 17.0e(also called daarsat), Arab2ab 28.0E(also called multitv), nns 7 22.oW(also called canalsat0. and a host of others. While 4.0meter dish can track satellite from African and middle east, 90cm and smaller dish can only track satellite positions that can be beamed with africa.
5. 60CM DISH
A 60cm dish performs all other functions of 90cm in Nigeria specifically and Africa at large except that it cannot track signal from few satellites. Most of us remember the period of avtar 2 that uses no sim card. To use avatar 2 then, you must use two dishe, one to track malagasy(w3a 7.0e) and the other one to track dstv. if you use a 60cm dish for example, you won’t get signal from w3a(also called malagasy).
A BOUT MOTORIZING A BIG DISH
Using a big dish like 4meter down to 3.0meters posses its own major headache, or let me call it inconvenience. Notable among these is the issue of mis-alligniment and susceptibility to wind. Secondly, you may consider a situation whereby you want to use your single 4meter or 3meter dish for all receivable satellite in your country. Now dish question arises; Must I call my satellite installer anytime i want to change the position of my dish from Nilesat to hotbird or vice versa?, Well the answer is no, there is a device called “jack”, This device will be mounted on your dish outside, and the control will be position in your living room inside and you will turn your dish from within to any satellite of your choice. The 3.5meter dish that is shown below can beam signal from dstv, malagasy, hotbird, nileatnss7 and many more merely by rotating it with a remote control from inside the house. This simplest explanation for this is with out external antenna that we control with a remote from within. So after installing your 2.4meter dish or bigger, please make sure you buy a jack along with it in other to motorize it.
MAJOR TYPES OF LNBFs WE USE IN AFRICA
We have two major types of LNBF, the first one is C-Band LNBF and the second is K-band LNBF. Ku band is now the most popular supporting satellites like nns7, amos, dstv, malagasy and a host of others. C-band works best with satellites like arabsat, nilesat, hotbird et.c
