## Long description

The Kathrein VOS 43/RA-1G2 F connector AC 230V 8W is a compact TV signal amplifier designed to improve reception quality for terrestrial and cable television installations. It connects using a standard F connector and is powered from a 230 V AC supply with a rated power consumption of 8 W. The unit’s metallic housing and moderate weight allow for flexible placement in home or light-commercial antenna systems where stable signal amplification is required.
Advantages
This amplifier provides stable gain to compensate for signal loss in cable runs and splitter configurations, helping to reduce pixelation and weak-signal interruptions. Its F connector compatibility ensures straightforward integration with common TV and antenna cables. The 230 V AC operation and low power draw make it suitable for installations without additional DC power supplies. The compact, metallic design supports installation in limited spaces while maintaining robust physical protection.
Suitable for
 Improving terrestrial TV reception in apartments and houses
 Compensating signal loss over long coaxial cable runs
 Use with splitters or multi-room TV distribution
 Upgrading older antenna installations to reduce interference
Key specifications
 Connector type: F connector
 Power supply: AC 230 V
 Power consumption: 8 W
 Housing: metallic finish
 Weight: 1.699 kg
 Form factor: compact inline amplifier
How to use
Install the amplifier inline between the incoming antenna/cable feed and the distribution cable or receiver, connecting coaxial cables with F-type connectors. Ensure the device is mounted in a dry, ventilated location and is accessible for maintenance. Connect the unit to a standard 230 V AC outlet using its power lead, then power on the connected equipment. Adjust any downstream receiver settings as required to optimize channel tuning after amplification.
Usage recommendations
Place the amplifier close to the signal source where possible to boost the signal before it traverses long cable runs or splitters. Avoid locating the unit near strong electromagnetic interference sources and ensure proper grounding of the antenna system. If multiple amplifiers or active devices are used, verify that overall gain does not overload receivers.
