В DVB-T2 4×4 car digital TV box is a specially designed receiver for vehicles that need stable and high-quality television signals while traveling at high speeds. Built to fully comply with the European DVB-T and DVB-T2 standards (ЭН300 744 / EN302 755), this advanced unit integrates four tuners and four active antennas с 25 усиление дБ, ensuring outstanding reception performance under the challenging conditions of a moving car.

В Европе, where DVB-T2 has been widely adopted as the official digital television broadcasting standard, automotive applications demand robust and flexible reception solutions. Traditional car TV boxes with only two tuners and antennas may provide acceptable reception in strong-signal urban areas, but they often fail on highways, rural roads, or cross-border travel zones where signal strength fluctuates. By contrast, а 4×4 tuner system uses diversity reception technology to constantly analyze multiple signals from four antennas, selecting or combining the best signal in real time. This dramatically reduces pixelation, interruptions, and loss of image when driving at high speed, even when passing through areas affected by multipath interference or Doppler shifts.

В Car DVB-T24 USB Box not only supports high-speed scanning and advanced signal processing but also offers versatile video outputs including CVBS and HDMI, ensuring compatibility with in-car entertainment systems. It supports PAL/NTSC formats, OSD teletext, subtitles, and even extra functions such as USB upgrade, HD media playback, and PVR recording. Power is conveniently supplied for active antennas through its +5V antenna output, making installation straightforward.
