Digital television has given us a beautiful and detailed picture, good sound. Terrestrial digital broadcasting has become widely available and in demand, despite the dominance of the Internet and numerous streaming services. However, for a good reception of the terrestrial digital TV signal, an appropriate antenna is required, which will not only steadily catch channels, but also demonstrate them in good quality. Such an antenna is Ritmix RTA-311-12 AVS.

Key Features
The amplifier board is located in an outer box made of high quality durable plastic. The case is reliably protected from moisture and ensures the operation of the amplifier even at low or extremely high temperatures.
The antenna itself is made of lightweight but strong aluminum alloy and is quick to assemble. The simple directional design turned out to be one of the most effective, the signal reception from the TV tower is stable and of high quality, without interference. The kit includes a strong mount that can withstand gusts of even the strongest wind. The total mass of the assembled antenna does not exceed one and a half kilograms.
Ritmix RTA-311-12 AVS provides reliable reception of DVB-T, DVB-T2 standard TV signal at a distance of 10 to 25 km from the broadcast tower. There is an opportunity to view HDTV. It is also possible to receive FM channels and listen to the radio directly on the TV (after appropriate channel settings).
Power is supplied via the IEC 61169 plug, which is found in any digital receiver (antenna input), so the device does not require additional wire and additional power. This sets Ritmix RTA-311-12 AVS apart from those competitors' products that require constant additional power supply from the electrical network. You can also connect the antenna directly to the TV if it does not use a TV set-top box (digital receiver). In this case, the antenna will receive terrestrial channels as passive, but will not be able to amplify a weak TV signal, since the TV does not supply power to the antenna amplifier through the antenna cable connector.
Comparison with competitors
The closest competitors of this antenna are products of such well-known brands as Locus, Delta, HARPER.It is worth comparing the offer from Ritmix with similar options from other manufacturers in order to highlight the main advantages and disadvantages of the product.
- Locus Meridian-12AF Turbo. This model is good for everyone: it provides the same powerful signal as the device from Ritmix, confidently picks up channels and supports digital TV standards. In the same way it is connected to the receiver or directly to the TV, in this case it is recommended to use the LI series power injector to power the amplifier. The injector is universal, it can be used with antennas of any brands with the same power principle. According to the results of our tests, Locus Meridian and Ritmix are models of good signal reception quality, convenient and easy to assemble, but Ritmix is more attractive in price.
- Delta H311A-01. This model is capable of simultaneously operating in the VHF / UHF bands, however, its signal gain is noticeably lower than that of the antenna from Ritmix. Also, to power the amplifier, a voltage of 12 V is required, which indicates the need to use a separate power supply. That is why Ritmix RTA-311-12 AVS is a much better option for home use.
- HARPER ADVB-2440. Outdoor antenna with active amplifier operating at frequencies 87.5–230 MHz, 470–862 MHz. In theory, it is omnidirectional due to the spherical shape of the body. But, judging by user reviews, in real life, such a case does not provide a high-quality signal. In addition, a direct current of 220 V is required to power the antenna amplifier. The advantages of Ritmix in this case are obvious.
