VHF/UHF amplifier GTV2129

Category:

Product Description

The unit is used to amplify VHF/UHF signals of 4 passive antennas and supply DC voltage to 3 active antennas without signal amplification.

Design

The unit is housed in a standard aluminium case with very good RF shielding and consists of the following sub-assemblies:

–    small signal gain amplifiers
–    coaxial relays
–    RF limiters

Special features

One amplifier channel is fed from two inputs with different polarisations. The selection of the polarisation will be done by a coaxial relay controlled via DC voltage (from amplifier output).
