Its compact dimensions and relatively low weight simplify installation in confined spaces. The device is engineered for low power consumption and operates from a standard mains supply, reducing the need for specialized power infrastructure. Robust connector types and metal enclosure ensure mechanical stability and shielding against external interference.
Suitable for
 Small to medium-sized TV distribution systems in homes and apartments
 Improving weak terrestrial or cable TV signals before splitters or long cable runs
 Use in equipment cabinets where compact amplification with F connectors is required

How to use
Install the Kathrein VOS 20/RA-1G on a stable surface or inside a distribution cabinet, securing it with appropriate mounting hardware. Connect the incoming antenna or cable feed to the amplifier input using an F-type coaxial connector and connect the output to the distribution line or first splitter. Ensure the unit is connected to a 230 V mains supply with the correct mains frequency. After powering on, check signal levels at downstream receivers and adjust system topology (splitters, cable lengths) as needed to avoid overload or insufficient signal. Follow local electrical safety regulations during installation and service.
Usage recommendations
To maintain stable reception, place the amplifier close to the signal source when possible, minimize the use of unnecessary splitters before the amplifier, and use good-quality coaxial cabling with correctly installed F connectors. Regularly inspect connectors and cables for corrosion or damage, and avoid exposing the unit to excessive moisture or heat to prolong service life.
