Podrobný popis
The preamplifier is designed for amplification of weak FM/DAB+ and DVB-T signals within 87-790 MHz frequency range. It can be used outdoors. The input and output impedance is 75 ohm - it means that antennas having 300 ohm impedance have to be equipped with a matching transformer e.g. C0001. The amplifier should be powered through the output (TV/12V) via the coaxial cable, from a 12 VDC power supply with RF/DC separator (also referred to as a DC injector).
