Antenna is an important part in the process of receiving signals sent by television or TV broadcasting sources or stations. By using a good TV antenna, the reception of images sent from the transmitting station is also good. We often see that there are TVs whose pictures are so clear, but there are also TVs whose pictures are so bad, blurry, and the picture doesn't even appear at all.
In general, the results of capturing images by television sets are directly linked to the antenna. No matter how good a television is, if it is not supported by a good TV antenna, the catching power cannot be maximized. Therefore, when we buy a TV set, we are advised to buy an antenna as well.
Actually, every television set is equipped with an antenna, but the type of antenna is small, whip. Often these antennas do not work properly. This means that the image received from the television station is not clear, blurry, even like a lot of ants.
Various ways are done so that the image received on the television set can be bright and clear. If the picture received by the television set is good, then we can enjoy broadcasts comfortably. Therefore, it is always strived so that television sets can receive shipments as well as possible. We do need a good television antenna to be able to receive good broadcasts.
Good TV Antenna - Tricks to Get Good TV Reception
Here's a trick to get good TV reception
1. Choose Antenna Series (Yagi)
Antenna series or yagi antenna is one form of antenna that is widely used for television broadcast receivers in this country. This is because the price is relatively cheap and simple. Yagi antennas do not require much equipment.
The use of a yagi antenna allows us to shoot the direction of the transmitter more precisely. On the other hand, interference from reflections from buildings around us, whether high-rise buildings or hills has very little effect. Meanwhile, the strength of this type of antenna is also influenced by its elements. The more elements that are owned or the longer the antenna, the greater the gain or gain will be.
Meanwhile, the favorite for a good television antenna is the UHF DX antenna because the resonance accuracy and the material for the antenna is really high quality. This type of antenna is often exhibited or promoted as an original antenna imported directly from Japan. Even though this is not the case, because the country has been able to produce this type of antenna.
2. Use 75 Ohm Coaxial Cable
To get a good broadcast image, we can use a 75 ohm coaxial cable. This type of cable used has attenuation or losses with small power, for example coaxial cable RG7, RG6 which has an attenuation of approximately 5 decibels (db) every 100 feet at a frequency of 750 Mhz.
We can also use RG11 coaxial cable which has an attenuation of 3.6 db/100 feet. This cable includes a large diameter so that if we use it, we will experience difficulties when installing it.
For the needs of a good cable, we must choose a cable that is really made of copper and not copper plated. Of course, because the material is made of genuine copper, the price of this cable is relatively more expensive than cables in general.
If you have a coaxial cable, choose one with tight fibers with a conductor diameter of about 1 mm. In order not to be deceived or mistaken when buying this coaxial cable, we can check it by peeling the end of the cable. If the cable is made of copper, the fiber conductors are brownish yellow.
Meanwhile, to be clear, the middle conductor can be scraped with scissors or whatever, if this is also brownish yellow to the inside, it can be ascertained that the copper wires. If the cable turns out to be a white center cable, it must be a coaxial cable with gilded material.
3. Set the Cable Length and Booster
One way to improve the reception quality of the television set, then we use a booster. In this position we must adjust the length of the cable used between the antenna and the booster. The best distance, based on installation experience is 1.5 meters in a straight position, without any coils in the cable.
4. Adjusting the UHF Trimpot
The trimpot setting is very important so that the RF power gain is not too large. This position is set in such a way depending on the distance of the position with the distance of the transmitter. If the distance is close, the trimpot is set to reduce power. But if the distance from the position to the transmitter is far, we adjust the trimpot in such a way that the amplification power increases.
5. High Antenna
The reception power of a television set is very dependent on the height of the antenna. For the size of the height of this antenna, the most appropriate is about 15 meters. This is the highest size, do not exceed this size.
6. Connector Connection
For good power reception, the connection of each component must be in good condition. We must ensure that each joint or connector is properly connected. We have to check the connection also make sure that everything is connected perfectly and correctly.
7. Roll the rest of the cable
For the installation of the antenna, we use the cable as a connector. In this case, we must pay attention to the length of the cable that we use. Generally, the length of the cable that we buy is long and more when installed. If this happens, then you should not roll the rest of the cable.
8. Antenna Shooting Direction
Another thing that really determines the reception power for a good reception is the antenna shot direction. If the direction of this shot is correct, the reception result must be good. If we shoot the antenna in the right direction at the transmitter, the antenna reception can be maximized. We need to be able to determine where the transmitter is located.
For reception with a long distance from the transmitter the angle of deviation required for the antenna is getting smaller. Thus, if in an area there is a group of transmitters received at a long distance. Then all the antennas can point to the existing transmitter. Of course we can point our antenna at these transmitters by taking the right angle of deviation.
We definitely need a television with good reception so that when we watch it we can be comfortable. If the display picture on the television is bad, then the eyes can experience fatigue. Eyes may be damaged if the picture on the television screen is abnormal. After all we want everything to be good, as well as the appearance on our television.
We make various efforts so that the picture display on our television is good and we are comfortable to enjoy the broadcast. We are very aware that if the impressions we see on television are not good, our television sets are equipped with various accessories that aim to improve the ability to catch broadcasts from television transmitters. We always hope that with these tools, we can be comfortable. We don't care how much money for it.
At least with the trick of making a good TV antenna as described above, we can be more practical and effective in dealing with the conditions.
