As in the case of analogue terrestrial television, antennas are required for digital terrestrial television (DVB-T) reception. Different types of antennas might be needed for reception depending on the distance to the transmission mast, the strength of the signal and the geographical of structural conditions. Antennas have to be aligned horizontally and/or vertically depending on the polarisation of the transmitter.
