Parabola is basically a type of dish-shaped TV antenna that is used to capture signals from various sources or transponders. Ideally, the larger the satellite dish, the easier it will be to pick up the signal.
More and more entertainment, both local and international that can be displayed. In times like today, of course choosing a satellite dish TV antenna is a must-have. This is also evidenced by the increasing use of satellite-based television.
Not many people know that the satellite dish itself has several different types. Though it is very important to know before you buy it.
1. The Net Parabolic Antenna (Mesh)
This type, also known as C-Band, is one of the most common and widely used. As the name implies, this satellite dish is shaped like a net that has small holes that function as reflectors.
Of the various size variations available, sizes 9 and 12 feeds are the most widely sold and commonly used, although others are.
This type of parabolic mesh or net is one of the most widely used because it has several advantages. Because it is made of aluminum which is light and not heavy, it will automatically have a long service life and will not rust easily.
In addition, the subscription fee which can be quite affordable is another reason why this antenna is widely used. However, there are definitely drawbacks.
One of them is located on the part of the wire mesh which is not firmly attached so that it is easily detached from the construction, or it can be said that it is also fragile. The level of catching power offered is a little less good when compared to other types.
2. The Solid Parabolic Antenna
Due to its higher subscription fee and slightly more complicated way of using it, there are fewer users of this antenna than the first type (net or mesh) satellite dish.
Usually only certain people, such as trackers, use this type, on the grounds that they can capture a wider range of signals, including those that are out of beam or difficult to obtain operating permits.
The size variations on the market are quite diverse, ranging from 4 feet to 8 feet which are quite easy to find and obtain.
This solid type parabolic antenna is actually divided into 2 depending on the reflector, namely:
- Offset focus: has an oval or oval shape with a fairly small diameter compared to other types. Only about 45 to 100 cm. Often found in the use of television channel subscriptions that are paid.
- Prime focus: has a round shape like the common parabolic antennas on the market. The sizes also vary, ranging from 4 feeds to 12 feeds, but the most commonly used size is 6 feeds.
3. The Mini Parabolic Antenna
Also known as the Ku Band. Generally more used by people who subscribe to the service provider pay tv.

In addition, as the name implies, in terms of the size of this antenna, it is smaller than the others. This advantage can save more space that you have.
4. The Frequency Type Parabolic Antenna
This type is probably the least common or familiar compared to other types on the market and known to the public. This type of satellite dish S Brand is used by pay tv.
The advantage of this antenna lies in the number of local channels that can be displayed more and more complete. Even some foreign television broadcasts can be witnessed.
It’s just that to watch the broadcast, you have to subscribe to premium separately, which means it costs more than it should.
Recently, parabolic antennas seem to be competing to show features that can attract users. It can be seen from the large number of satellite dishes that have been circulating in the market today.
Even so, the final decision what to choose is in the hands of the user himself. Because each dish antenna must have its own advantages and disadvantages.
