TV-signaalinvahvistin Kathrein VOS 43/RA

The Kathrein VOS 43/RA is a compact TV signal amplifier engineered for reliable performance in terrestrial and cable reception systems. Designed with F-type connectors and low power consumption, the unit supports consistent signal gain while maintaining a small physical footprint of 184 x 134 x 63 mm and a weight of 1.4 kg. The amplifier operates from a standard 230 V, 50 Hz mains supply and is suitable for installation where stable amplification and minimal power draw are required.

Advantages

The amplifier provides stable signal amplification with low typical power consumption of 5 W, which reduces operating costs and heat generation. Its compact housing and standardized F connectors simplify mounting and connection in distribution boxes or near reception equipment. A robust construction ensures long-term operation in domestic and small commercial environments, while compatibility with common 230 V mains makes integration straightforward.

How to use

Mount the Kathrein VOS 43/RA in a dry, ventilated location close to the antenna feed or distribution point. Connect the incoming antenna or cable feed to the input F connector and route the amplified output to the distribution lines or the TV receiver using the output F connector. Ensure the unit is connected to a 230 V, 50 Hz mains supply and that all connections are secure. After powering the amplifier, verify signal levels at the receiver and adjust downstream components as needed to avoid overload.

Recommendations

Place the amplifier away from direct heat sources and in an area with adequate airflow; avoid exposure to moisture. Use quality coaxial cables and properly tightened F connectors to minimize losses. If multiple amplifiers or splitters are used in the system, check cumulative gain and adjust attenuation or spacing to maintain optimal signal levels.
