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.

• Location: built-in

• Amplification: 15 dB pri 5-24 V DC

• Noise figure: 2 dB

• Power supply current : enosmeren tok 5-24 V 83 mA pri 5-24 V DC

• Power supply source : via coax. cable

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.

• Location: built-in

• Amplification: DIGI-LOG 14VU: 14 dB at 5 V DC ; DIGI-LOG 14U: 16 dB at 12-24 5 V DC

• Noise figure: 2 dB

• Power supply current : 5-24 V, 12 mA pri 5 V DC in 30 mA pri 12-24 V DC

• Power supply source : via coax. cable

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.
