DVB-T & DAB

The conversion of baseband audio-video (A/V) signals to radio frequency (RF) channel is called modulation. The process allows for the distribution of signals coming from all kinds of sources, such as computers, DVD and Blu-ray players, security cameras etc. through antenna systems.

Digital Audio Broadcasting (DAB) is one of digital radio technologies for broadcasting radio stations, used mainly in Europe. As in the case of digital terrestrial DVB-T that replaced over the years analog TV broadcasting, digital radio offers a range of benefits both for broadcasters and listeners.

Professional approach to the problem of amplification of television signals in modern DVB-T and SMATV systems is the use of channel amplifiers, which allows for precise gain control and noise reduction.

Our intention in creating this document was to inform prospective investors, project offices and installation companies on the issues connected with (S)MATV / shared antenna systems, in particular, their modernization and adaptation to the requirements of DVB-T.

Digital terrestrial television (DVB-T/T2) covers the whole Europe. These several examples of DVB-T antenna systems will help anyone who wants to build a new antenna system or upgrade the existing one. The antenna installations presented below are a set of options that can be selected depending on the power of the transmitter and its distance to the reception point, as well as specific requirements of the user(s).

An article on the measurements of signals in DVB-T systems. It explains the meaning of the measured values for the quality of reception. The part concerning the amplification of the signals allows for better choice of RF amplifiers, especially in the transitional period (from analog to digital TV).
