The Sencor SDA 212 indoor antenna is suitable for places located closer to transmitters or in large cities / Sencor
The transition to the new generation of DVB-T2 terrestrial broadcasting offered viewers a picture of razor sharpness, and statistics for interesting data. These show that 51% of people use a common antenna to receive a television signal, 42% rely on an outdoor antenna and the rest on a indoor antenna.
Last two types also represent the new products SENCOR SDA 532 and SDA 212. Among the most frequently asked questions of television viewers are traditionally – which antenna to buy, which is the best? Although it is clear to everyone that the antenna can be to blame for the annoying image cube, there is no universal advice.
Even professionals in the field claim that different places require different types of antennas and where the inhomogeneous signal is disturbed by reflections, it is necessary to use a measuring device before installation. They are also well aware that no special DVB-T2 antenna, as some manufacturers have misleadingly mentioned, exists.
The suitability of the receiver is determined purely by tuning it to certain frequencies. DVB-T2 transmits in the UHF band, which is narrowed to channels 21-48 resp. frequencies from 474 to 694 MHz (previously the range of channels was 21-60 and 474-790 MHz, respectively).
Nevertheless, there are tips to follow. For example, the directionality, gain, and quality of an antenna amplifier play a critical role in receiving weak multiplexes. At present, there is a wide range of outdoor and indoor antennas reminiscent of design accessories rather than functional technical aids. That’s why a guide from 50 years. The 20th century to the construction of a “home-made” antenna with isolated egg trays evokes only a forgiving smile today.
The new Sencor SDA 532 antenna’s shape evokes the flying saucer of an alien civilization. In fact, it is an omnidirectional outdoor antenna, which should be the first choice for those whose signal reception lags.
Expert measurements show that older antennas tuned to the whole band of channels are worse off with the strength of signal reception, especially at the beginning of the band. Thus, if the viewer has problems with reception of, for example, channel 26 (multiplex 21 ČT) or channels 22 and 23 (multiplex 23 CDG in Prague, Central and South Bohemia), the new antenna can improve the reception by a lot. The Sencor SDA 532 antenna already includes a 5G LTD filter to prevent interference from the mobile operator’s signal. It offers various mounting options and is resistant to external weather conditions. SDA 532 is available on the Czech market for CZK 799.
The indoor antenna, represented by the Sencor SDA 212 type, on the other hand, is suitable for places located closer to transmitters or for large cities. In addition to the reliable function, it builds on subtle dimensions so that it takes up as little space as possible in the living room, where the television is most often placed. Which also applies to its placement to the window.
The advantage of this antenna is, in addition to easy positioning and thus a change in polarization, also power supply directly from the TV via a micro USB cable. This antenna is also on sale for CZK 339.
