Abstract (en)
[origin: WO2006119999A1] The invention relates to an antenna diversity in which high-frequency signals (HF signals) received via a plurality of antennas are fed to a respective tuner (1, 3). The invention is characterized in that the intermediate frequency output signals (IF signals) of the tuners (1, 3) are fed to a connect-through device (5) that connects one IF signal each through to one subsequent demodulator (6).
