## Summary description

Opticum W-20 is an antenna amplifier designed to boost terrestrial TV and FM radio signals for improved reception. The compact device connects inline with an antenna feed to increase signal strength and reduce loss over cable runs. Suitable for use in homes and small installations to enhance picture and sound quality where signal levels are weak.

## Long description

Opticum W-20 is an inline antenna amplifier designed to increase terrestrial TV and FM radio signal strength for improved reception. The compact unit connects between the antenna and the coaxial cable run to compensate for signal loss over long cables and weak reception areas, helping to stabilise picture and sound quality in home and small installation environments.
Advantages
The amplifier provides a controlled gain that improves signal-to-noise ratio and reduces pixelation and audio dropouts without altering channel tuning. Its compact form factor allows convenient placement near the antenna or in an equipment cabinet, while the coaxial input and output ensure straightforward installation with standard cables. Built for passive inline use, the device minimises additional clutter and can extend the effective reach of existing antenna cabling.
Suitable for
Homes with weak terrestrial TV reception
Small apartments and flats with long coaxial cable runs
FM radio reception improvement in residential setups
Supplementing roof or outdoor antennas where signal loss is observed
Key specifications
Function: Terrestrial TV and FM radio signal amplification
Connection type: Inline coaxial connector compatible with standard antenna cables
Form factor: Compact inline housing suitable for near-antenna or indoor installation
Use environment: Designed for home and small-installation applications
Primary effect: Compensates for cable loss and increases received signal level
How to use
Install the Opticum W-20 inline between the antenna and the coaxial cable leading to the receiver or distribution point. Ensure connectors are tightened to provide a secure electrical connection and avoid sharp bends in the cable near the device. After installation, scan or retune your TV or radio receiver if necessary to confirm stable reception and channel availability. If reception does not improve, check antenna orientation, cable condition, and grounding before repositioning the amplifier.
Usage recommendations
Use the amplifier primarily to counteract signal loss from long cable runs or marginal reception; avoid excessive cascading of amplifiers as this may introduce noise or overload receivers. Maintain weatherproofing and secure mounting when placing the device outdoors or near an external antenna, and inspect cable connections periodically to ensure optimal performance.
