3 Facts You Must Know about TV Transmitter Station

 

Let's have a simple understanding of the TV transmitter station first before we learn about the transmitting equipment used in the TV transmitter station. 

The Aim is to Transmit TV Signals

As the name suggests, the TV transmitter station is mainly used for transmitting the audio signals and video signals outward. It contains the TV broadcasting equipment working for transmitting TV signals, including the TV broadcast transmitter, TV transmitting antenna, the Studio Transmitter Link receiver equipped with an antenna, etc.

The Location Should be Setting as High as Possible

Typically, the TV transmitter station would be built on the top of the mountain, usually miles away from the TV station. Because every TV broadcaster wants to make, TV signals cover a more extensive range at less cost and the way of installing the TV transmitting antennas as high as possible costs less.

 

How to Improve My TV Signals?

1. Installing Your TV Transmitting Antennas Higher

The audio signals and video signals are radio waves. If some high buildings block them, the TV signals would be weakened and can't reach the place far away. So installing the TV transmitting antennas higher is an excellent way to avoid the obstacles.

2. Choosing the Best TV Broadcast Antennas

The best TV broadcast antenna should be high-gain and withstand high transmitting power. A high-gain antenna can concentrate the energy used to transmit radio waves, and the TV signals can reach farther.

3. Selecting a High Power TV Broadcast Transmitter

Replacing a high-power TV broadcast transmitter is also a way for enlarging the coverage because TV signals with more power have a better capability of going through the buildings.

 

How Does a TV Transmitter Station Work?

 

Before the TV transmitter station broadcasts the TV signals outward, it should first receive the signals from TV stations. So the broadcast equipment works together in 3 steps as follows:

Step 1

The UHF TV transmitter Receives the audio signals and video signals from TV stations through Studio Transmitter Link receiving antenna.

Step 2

The signals are moved to the TV transmitter, processed, and converted into current signals.

Step 3

The current signals are transferred to the TV antenna attached to the Radio Tower and generate radio signals to broadcast.

 

Now you have a clear concept of the operation of the TV transmitter station. Next, let's learn about what television broadcast equipment is used in the TV transmitter station.

 

Common Transmitting Equipment Used in a TV Transmitter Station

 

There are at least 3 kinds of equipment in a TV transmitter Station, including a TV broadcast transmitter, TV transmitting antenna, and studio transmitter link equipment, etc. 

1. Television Broadcasting Transmitter

  • Definition - A TV broadcasting transmitter is a kind of transmitting equipment for broadcasting audio signals and video signals. It takes the role of receiving the audio signals and video signals from Studio Transmitter Link transmitter, processing signals, and converting them into current signals. Finally, the signals will be transferred to the TV transmitting antenna.

 

  • Types - Usually the TV broadcasting transmitter can be divided into the analog television transmitter and digital television transmitter in modulation method. Now more and more countries are eliminating analog TV transmitters and promoting digital ones because the digital television transmitters can not only broadcast more channels but also broadcast high definite video and high-quality audio signals.

  • Frequency - The available radio frequency ranges for the TV broadcasting transmitter are VHF and UHF. And each TV channel takes over the bandwidth of 6 MHz. The following are the frequency band in detail:

 

54 to 88 MHz for channels 2 to 6

174 to 216 MHz channels 7 to 13

470 to 890 MHz for UHF channels 14 to 83

 

A wider range of frequencies comes with more transmitting channels. It means that you can broadcast more programs and earn a more extensive range of viewers. 

 

2. Television Transmitting Antenna

A TV transmitting antenna is essential for transmitting TV signals. The electric current on the TV antenna will create radio waves and the antenna would transmit them. In addition, the TV broadcast antenna can help improve the TV signals and adjust radio waves' intensity and direction as you want.

 

Typically, there are mainly two types of TV transmitting antennas used in TV broadcasting: VHF & UHF TV panel antenna and UHF TV slot antenna.

 

  • VHF or UHF TV Panel Antenna

The panel TV antenna is used in the frequency range of VHF and UHF. Because it can only transmit signals at an angle of 90 °, it is a directional antenna.

 

  • UHF TV Slot Antenna

The slot antenna is a kind of UHF TV antenna. Different from panel antenna, it is a type of omnidirectional antenna, which means that a single slot antenna can send radio signals in all directions. 

 

Here are the advantages of the UHF TV panel antenna versus the UHF TV slot antenna

 

UHF TV Panel Antenna UHF TV Slot Antenna
  • It has higher radiation efficiency

 

  • It is especially suitable for point-to-point transmission

 

  • When it forms an antenna array, it has higher bandwidth

 

  • It has a smaller volume, lighter weight, easier disassembly, and convenient transportation, which greatly reduces the transportation cost of the operator.  
  • Its wind loading is lower, reducing security risks

 

  • It is an omnidirectional antenna, which can meet various requirement

  

  • It is a completely closed antenna with a long service life

 

  • It has a simple structure and uses fewer cables and connectors than the TV panel antenna, and low failure probability.

 

     

    3. Studio Transmitter Link

    As we mentioned before, a TV transmitter station needs Studio Transmitter Link to receive the TV signals from the TV broadcast station.

      

    Studio Transmitter Link is a kind of point-to-point broadcast system, and it can be used in long-distance transmission. It allows the TV transmitter site to be built in the best place for TV signals transmission as possible as it can.

    How to Choose the Best TV Broadcast Equipment?

     

    TV broadcasting is such an essential public service that it highly requires TV broadcast equipment. So for people who want to build up a new TV station, it is important to know how to choose the best TV broadcast equipment.

    Quality Assurance

    The quality of TV broadcast equipment should be ensured. A high-quality TV broadcast equipment comes with reliable and long-range transmission capability and the lowest rate of failure. In addition, a TV broadcast transmitter with a larger bandwidth can help you earn more viewers with more channels and bring TV broadcast companies more benefits.

    User Friendliness

    A good product should consider user operation preference, so user-friendliness is essential. So does a TV broadcast transmitter and TV broadcast antenna. It should be designed to suit the user's preference.

     

    For example, a TV broadcast transmitter should be equipped with a clear screen for operation and allow the operators to finish setting in a short time. And a TV transmitting antenna should be easily installed, and it can reduce the difficulty for installing and maintenance.

    Safety and Protection

    Safety and protection programs are important for any TV broadcast equipment. Such as TV broadcast transmitters, it is impossible to monitor its status at any time. If it can stop working before breaking down, it can timely avoid damage to the machine and the other equipment around.
