TV antennas for receiving digital terrestrial TV

What is a television antenna?

A television antenna is a device whose task is to capture the signal from a television transmitter and transmit it to the receiver. The signal from the transmitter is transmitted in the form of an electromagnetic wave. The TV antenna then turns it into an electrical signal and transmits it to the TV set, which in the next step converts this signal into a picture.

How does a television antenna work?

A TV antenna is designed to receive the signal sent by its sender. This signal is then transported via a cable to a set-top box or TV set, which are equipped with a built-in tuner. Decoding of the signal then takes place so that the TV can play the selected TV channels. In the case of dish models of TV antennas, the metal canopy reflects the signal, which then goes to the converter, to which the antenna cable is connected.

Why is a TV antenna important?

A TV antenna is a basic device that is essential for receiving terrestrial television. Choosing the right device is crucial, because it is the TV antenna (in combination with the right coaxial cable) that affects the strength and quality of the signal delivered to the receiver. Different TV antennas differ from each other in the place of installation and the range of frequencies received.

Outdoor and indoor TV antennas

A TV antenna should be selected according to our individual needs. When choosing a TV antenna, the first thing to consider is where you want to mount it. After all, terrestrial antennas can be installed in two different configurations - internally and externally.

The main difference when it comes to outdoor tv antennas and indoor tv antennas is the type of amplifier inside.

Internal antennas work well only if they will be in close proximity to the transmitter. Their performance may also depend on the type of room, as well as the thickness of the walls or the location of the furniture.

An outdoor TV antenna will provide a much better signal. Outdoor TV antennas also provide much better installation possibilities due to the possibility of mounting them at a height that will allow the best signal reception. Thus, an outdoor antenna is best mounted on a balcony, roof or window.

Outdoor TV antennas are further divided into:

• directional TV antennas,
• wide-angle TV antennas,
• omnidirectional TV antennas.

How to choose a TV antenna?

As we have already mentioned, the choice of a TV antenna is not simple. The antenna installation should be selected individually to local reception conditions. Therefore, several factors should be taken into account.

When planning the purchase of an antenna, it is necessary to determine: the location and directionality of the TV transmitter in relation to the place of reception, the configuration of the terrain between the transmitter and the antenna, its power, buildings (city, open area), forest cover and the height at which you plan to hang the tv antenna. Among these parameters, you should also pay attention to the type of signal received. After all, antennas can receive only TV signals (VHF and UHF) or TV/radio signals (VHF, UHF, FM, DAB+).

Where to mount a tv antenna?

The installation of a TV antenna is best carried out on the roof of the house, because then the signal from the TV transmitter will be undisturbed by various obstacles, such as other buildings in the city or terrain obstacles outside the city. A balcony, its railing or a wall is also a good place. In the case of a satellite dish, we point the device to the south, while a terrestrial antenna should face the direction of the TV transmitter.

We can proceed with the installation of a TV antenna on our own, but for safety reasons it is worth hiring specialists from an installation company. Professionals from our store will be happy to help you choose the right TV antenna and suggest how to install it. Check it out!
