What was a DVB-T antenna?
DVB-T antennas enable the reception of analogueue and digital TV channels (DVB-T and DVB-T2) in range. With an antenna cable, the signal is then transmitted to the set-top box or the DVB-T tuner integrated in the TV set. DVB-T antennas can be used with (active) or without (passive) integrated amplifier. Many models also receive DAB and DAB+ radio signals as well as FM radio.
TV signals via DBV-T (Digital Video Broadcasting - Terrestrial) can be received in large parts of Europe as well as on other continents. They are spread like radio signals via transmitter masts. The received programs as well as the signal strength can vary greatly at different locations and are distributed among the frequency ranges UHF (470 to 862 MHz) and VHF (174 to 230 MHz), which are also used in the radio.
What DVB-T antennas are there?
Basically, a distinction is made between active and passive DVB-T antennas. Active DVB-T antennas are equipped with integrated amplifiers, which can also process a bad signal. However, the built-in amplifiers often depend on an external power source.
| DVB-T flat antenna | DVB-T flat antennas can be used as practical flat boxes, especially indoors, but can also be used as active or passive devices in outdoor areas. |
| DVB-T roof antenna | Active roof antennas protect the integrated amplifier in a robust housing and thus visually resemble flat antennas. The passive version offers good reception in the form of a directional antenna. |
| DVB-T rod antenna | Small active and passive rod antennas are mainly designed for indoor use. Some models can also be used outdoors. They are hardly noticed by their compact size. |
| DVB-T, TELESCOPIC ANTENNA | Active as well as passive DVB-T telescopic antennas offer especially many setting options for optimum reception in the UHF and VHF frequency ranges. |
The most important purchase criteria for DVB-T antennas
Application area
- Only use suitable DVB-T antennas with the corresponding IP protection class outdoors (IP55 and later)
- Space-saving models are available for indoor use
The suitable antenna shape for optimum reception
- Rod antennas and flat antennas for inner-city locations with proximity to the transmitter mast
- Roof antennas and telescopic antennas for rural areas with low signal strength
The right equipment
- Passive antennas are usually sufficient when the signal strength is good
- Active antennas with amplifiers for regions with low signal strength
Technical extras
- Additional reception of DAB/DAB+ for digital radio
- Additional FM reception for classic radio stations
- Mounting aids for outdoor use on the roof or on the Facade
- LTE/W-LAN/GSM filter to avoid interference
Power consumption
- Active DVB-T antennas require a power source for their amplifier
Tekkie tip for signal strengths
Since the transmission areas differ greatly in terms of signal strength and the program transmitted, a closer look at a transmission card is recommended. Thus, the suitable antenna can be selected with or without amplifier. Changing the shape of the antenna can also achieve better results.
The suitable location of the DVB-T antenna
The receiver displays signal quality and signal strength are particularly helpful for the optimum alignment of DVB-T antennas. Radio signals can be affected by many disturbances. These include dense cultivation or plants as well as strong weather events such as thunderstorms. The position of the DVB-T antenna can also affect the reception quality in the indoor area. We recommend primarily location close to windows and locations that are not located in the basement. The location in the room also influences the reception quality. It can be helpful to position rod antennas horizontally.
Installation is a little more complex in outdoor areas. Roof antennas must be aligned for reception, was supported with appropriate measuring devices. In principle, DVB-T antennas should be installed in the outdoor area as free of interference as possible. Antennas for mounting under the roof are also available. For this purpose, the outer side facing the transmitter mast is selected. In addition, make sure that suitable cables are used, especially for active DVB-T antennas, which must be connected to a power source. A test run is recommended before final assembly.
The most frequently asked questions about DVB-T antennas
Can you also receive DVB-T2 channels with a DVB-T antenna?
Yes, because the reception width of the antennas covers the transmission frequencies of DVB-T and DVB-T2. However, if DVB-T frequencies are to be used elsewhere in the next few years, the use of frequency filters will be required.
Can a DVB-T antenna be connected to the PC?
If the PC or laptop has suitable hardware and software, an indoor antenna can be connected to it. For this, a DVB-T stick is required as an adapter between antenna cable and USB.
Do you need a receiver to receive DVB-T?
The DVB-T antenna serves only as a receiver. Modern TV sets often have built-in DVB-T tuners for support. However, these can also be supplemented in the form of set-top boxes.
How to connect a DVB-T antenna?
With an integrated tuner, the DVB-T antenna can be connected directly to the TV with the antenna cable (coaxial). If a DVB-T receiver is connected, the DVB-T antenna provides the input. The signal is then transmitted to the TV set, for example, via an HDMI cable. Active DVB-T antennas receive the power supply either through a power supply or from the receiver.

In the core area and in the inner city
Thanks to the extensive placement of the transmitter masts, the signal strength in inner city locations is usually excellent. For such areas, passive DVB-T rod antennas already offer sufficient reception. Due to dense construction and diverser disturbances, however, the switch to an active variant with amplifier (40 dB and more are possible) can be recommended, especially in solid buildings made of reinforced concrete. If interference occurs when flat or rod antennas are used in the VHF range, a telescopic antenna can be a suitable choice.
In peripheral areas of the transmission area in the peripheral areas of the transmission area, active outdoor antennas are particularly recommended, as the signal strength is not particularly high here. If you want to receive radio stations via the DVB-T antenna, you can provide a good reception with suitable outdoor antennas. Depending on the location, indoor antennas with amplifiers may also be sufficient.
