Antenna Amplifiers for YAGI antennas - - Thiết bị tự động hóa công nghiệp - ANS Vietnam

Amplifier DIGI-YAGI can not be used with YAGI antennas whish serial have DTX dipole (all YAGI UHF antennas ).

Amplifier has "F" female connector and impedance 75 Ohm.

It's especially designed for the digital terrestrial signal's (DVB-T) reception. 




 

Example: how to increase the antenna gain.

We're selling it in two versions:

1) as a independent unit
DTX dipole's plastic box must be opened and replaced the existing passive balun with this amplifier.
Tools are required for this intervention.

2) as an active DTX dipole
Amplifier is already installed inside DTX dipole.
It is necessary to replace the existing passive DTX dipole with DTX dipole with built-in amplifier.
Tools aren't required.


Amplifier can be supplied with outside power supply* or directly with digital terrestrial DVB-T receiver.
Power supply is provided through the same coaxial cable as reception signal.
