As you know, to watch TV programs, in addition to the TV itself, you need an antenna. In this article, we will tell you how to choose an antenna for a TV and place it correctly, for a stable and high-quality reception of a television signal. And also briefly describe the basic structure of various types of antennas.
They can conditionally be divided into three main types:
What are their main differences, and which device is best suited exactly in your case? Below we will consider these issues in more detail, and you yourself decide which device is best to choose.
This type of device, as is already clear from the name, is intended for installation directly in the premises. Due to the weak signal reception power, it is recommended to use them only in the zone of reliable broadcast reception (approximately 30 kilometers from the television center or repeater). To increase power, it is best to use a television signal amplifier complete with it. So you can significantly improve the quality and stability of the received signal. Indoor antennas come in two forms:
- rod type;
- frame type.
The rod-type indoor antenna operates in the meter range and has from 2 to 4 whiskers, which are signal receivers. The length of the mustache depends on the design, so it can reach one meter. They are mounted on a stand, inside it there is a matching transformer, through which a signal is transmitted directly to the TV input through a connecting coaxial cable. The mustache usually has a telescopic structure, which, combined with the low weight of the entire structure, provides it with great mobility.
Setting up the reception is reduced to changing the position of the mustache vibrators in space and relative to each other. However, before choosing a device of this type, one should take into account the minus of this setting is that with the normal reception of one channel, others may work unstably. Therefore, if you do not want to configure each channel individually before viewing, you will have to look for a “golden mean” when setting up all channels.
The antenna of the frame type, operating in the decimeter range, consists of an open metal circuit (frame) mounted on a stand, as well as connected to the receiving socket of a television receiver via a coaxial cable. Also, as a rod, it is quite limited in its capabilities, therefore, to improve reception, it is best to use an amplifier for television signals with it. Wide-range log-periodic antennas of the frame type have proven themselves excellently.
Video: Which Antenna To Choose For A TV
If you live near a television center or repeater, are confident in the stability and strength of the received signal, then you can choose a room antenna for the TV. On this purchase, you can significantly save, as the price of these devices does not exceed 700-800 rubles.
If for some criteria an indoor antenna does not fit you, then you should think about purchasing an outdoor antenna. There are many different designs for this device. Therefore, we won’t describe them all, and to help you choose the right device for your TV, we’ll limit ourselves to a general overview, as well as recommendations on operating features.
Manufacturers produce two main types of these devices:
Active are sold complete with a power amplifier and are designed to provide reception in conditions where there is interference to the signal. A lot of factors, such as:
- remote location from the broadcast source;
- obstacles dispersing the broadcast (houses, other high-rise objects, trees, power lines and so on);
- a lowland located between the receiving point and the tower;
- weak or unstable TV tower or repeater signal.
Passive are acceptable if the TV tower is on the line of sight and there are no obstacles that impede the reception of the broadcast.
However, if you live too close to the broadcast source, then the received signal may be distorted due to excess power. In this case, you may need a special device that attenuates a strong signal. the attenuator.
By design, the outdoor antenna can be rod, frame (loop) or mixed type. A rod antenna, due to its low power, is best used as a passive one. The loop antenna is best used in conjunction with an amplifier, then it will provide reliable reception of the television signal, in the absence of significant interference on its propagation path, at a distance of even more than 50 km from the signal source.
To correctly select an outdoor antenna for a television receiver, focus on the above characteristics, based on the characteristics of the operating conditions.
Satellite, otherwise called parabolic, although they are in a completely different price category than the above, however, they are becoming more widespread among the population. This is primarily due to the stable and high-quality reception of a much larger number of channels than is possible with a simple external or internal antenna.
A satellite dish for a TV consists of a directly receiving device and a receiver, by which this signal is decoded. Since it receives the signal directly from the satellite, the quality and stability of the television signal directly depends on the location of the antenna relative to the broadcast source (satellite), which must be taken into account when installing it.
Satellite antennas, as we mentioned above, have the most stable signal reception, image quality, as well as the number of received channels, which can be expanded by connecting paid packages. Only atmospheric precipitation, such as heavy rain or snow, can prevent stable reception of a satellite dish.
So we examined the most common types of antennas sold by us. We hope that our article has helped you learn something new for yourself and choose a suitable antenna for your TV from the variety that is presented on the modern market for these devices.
