Product information

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.
