What is the Working Principle of Dish Antenna?
The dish antenna receives radio frequency (RF) energy and then converts this energy into an electrical signal. This electrical signal is then sent to the television or radio receiver. Dish antennas consist of a parabolic reflector that can receive high frequency electromagnetic waves and an antenna located in the center of this reflector.
The antenna collects radio frequency signals and reflects these signals to the parabolic reflector. The reflector reflects these signals towards the focal point where they are received with an LNB (Low Noise Block). The LNB processes the signals at the focal point through amplification (amplification) and conversion (conversion) processes. As a result of this process, at the LNB output, the signals are converted to lower frequencies and then sent to the receiver. These low frequencies are the signals required for the television or radio receiver to view or hear the satellite broadcast.
Dish antennas are the most common antennas used to receive satellite broadcasts and have many advantages. However, it is important to have the correct setup and adjustment, otherwise the signal quality may deteriorate or the reception may be interrupted.
What are the Dish Antenna Types?
There are different types of dish antennas according to the type of broadcast and the satellite broadcasting the satellite. Here are some types of dish antennas:
Single output dish antennas: They are designed for the use of a single receiver. These antennas are connected to the satellite receiver via a single cable.
Multi-output dish antennas: They are designed to distribute satellite broadcasts to more than one receiver. These antennas have multiple outputs on the LNB and each output is connected to a separate receiver.
Mini dish antennas: Thanks to their small size, they can be used as built-in antennas or in tight spaces such as apartments.
Motorized dish antennas: These antennas can receive different satellite broadcasts by turning towards the satellite. In this way, it is not necessary to manually adjust the antenna to watch different satellite broadcasts.
Fixed dish antennas: These antennas are held in a fixed position towards a particular satellite and can only receive broadcasts from that satellite.
Fiber optic dish antennas: These antennas convert satellite signals into fiber optic cables and then distribute them. In this way, signals can be transmitted over longer distances and there is less signal loss.
Smart dish antennas: These antennas can be controlled via internet connection and automatically find the best satellite signal.
These types of dish antennas are designed to meet different needs and are used for monitoring satellite broadcasts.
What are the Advantages of Dish Antennas?
Dish antennas have many advantages. Here are some:
Wide coverage: Dish antennas can receive satellite broadcasts in a wide coverage area. Therefore, you can watch satellite broadcasts from anywhere in the world.
High quality picture and sound: Satellites provide high quality picture and sound signals. Therefore, they allow watching and listening to television and radio broadcasts in high quality.
They are long-lasting: Because they are made of quality materials, satellite dishes are long-lasting and can be used for years.
Multi-receiver: Multi-output dish antennas can distribute satellite broadcasts to more than one receiver. Therefore, you can watch different broadcasts on different devices over the same antenna.
Affordability: Dish antennas are generally more affordable than other satellite reception devices. Therefore, they are preferred by home users.
Satellite conversions: Motorized dish antennas can receive different satellite broadcasts by turning towards the satellite. In this way, it is not necessary to manually adjust the antenna to watch different satellite broadcasts.
Digital compatible: Dish antennas can also monitor digital satellite broadcasts as they are digital compatible. Therefore, they are an ideal choice for adapting to new technology.
Dish antennas are one of the most common and practical ways to monitor satellite broadcasts and have many advantages.
How Much Do Dish Antennas Cost?
The price of dish antennas varies according to the quality, size and features of the antenna. In addition, there may be differences between brands, price differences depending on the type of antenna and the region of purchase. In general, smaller sized dish antennas are more affordable and can usually cost between 100-300 TL. Medium-sized dish antennas can vary between 300-700 TL.
Larger dish antennas, on the other hand, can start from 700 TL and go up to thousands of liras. Motorized and multi-output dish antennas may be more expensive. In addition, antenna installation and satellite receiver are other factors that can increase the cost. Therefore, when purchasing a dish antenna, we recommend that you choose a quality and affordable one, taking into account your needs and budget.
