Antenna amplifier with SWITCH system DIGI-LOG 15 R-U
Amplifier is built inside antenna carrier in all LOG antennas with mark "DTT/G".
Amplifier can not be installed into other LOG antennas (LOG antennas with mark F, FZ, F H/V).
Amplifier has "F" female connector and impedance 75 Ohm.
It's especially designed for the digital terrestrial signal's (DVB-T) reception.
Amplifier can be supplied from outside power supply* or direct from digital terrestrial DVB-T receiver.
Power supply is provided through the same coaxial cable as reception signal.
If the antenna with this amplifier is supplied by the power supply it works as active antenna.
Total gain of active antenna = gain of antenna + amplification of amplifier DIGI-LOG 15 R-U
If the antenna is not supplied by the power supply it works as a passive antenna. It's gain is same as a gain of antenna without amplifier.
Total gain of passive antenna = gain of antenna
Amplifier DIGI-LOG 15R-U has impedance 75 Ohm and has built-in 4 frequency notch filters (stop filters), which throttle frequencies:
- TETRA 400 (350 - 460 MHz)
- GSM 900 (890 - 970 MHz),
- all frequencies higher than 1000 MHz
* Power supply is not included. Suitable power supply is [LINK id="2011070712244953"]SUR-211[/LINK].
Antenna amplifier DIGI-LOG 14VU / DIGI-LOG 14U
Amplifier is built inside antenna carrier in all LOG antennas with mark "DTT/G".
Amplifier can not be installed into other LOG antennas (LOG antennas with mark F, FZ, F H/V).
Amplifier has "F" female connector and impedance 75 Ohm.
It's especially designed for the digital terrestrial signal's (DVB-T) reception.
Amplifier can be supplied from outside power supply* or direct from digital terrestrial DVB-T receiver.
Power supply is provided through the same coaxial cable as reception signal.
If the antenna with this amplifier is supplied by the power supply it works as active antenna.
Total gain of active antenna = gain of antenna + amplification of amplifier
If the antenna is not supplied by the power supply it doesn't work.
* Power supply is not included. Suitable power supply is SUR-211.
