## Summary description

Antenna amplifier opticum WA-20 (model WA-20) is a compact device designed to boost terrestrial TV antenna signals. It increases signal strength to improve reception quality for DVB-T/DVB-T2 or analog broadcasts when installed between an antenna and TV or set-top box. Suitable for reducing signal loss on long cable runs and for areas with weak reception.

## Long description

The opticum WA-20 antenna amplifier is a compact inline device engineered to increase terrestrial TV antenna signal strength for DVB-T/DVB-T2 and analog broadcasts. Designed for installation between an antenna and a television or set-top box, it compensates for signal attenuation caused by long cable runs and marginal reception conditions. The amplifier helps stabilize picture and sound quality where the received signal level is low, while maintaining a simple, space-saving form factor that fits into standard coaxial cable installations.
Advantages
The opticum WA-20 improves reception quality by amplifying weak terrestrial signals and reducing the impact of cable losses. Its compact design allows easy placement close to the antenna or near the entry point of a building without requiring additional mounting space. The unit provides a straightforward way to enhance DVB-T/DVB-T2 and analog broadcast performance without changing antenna geometry or upgrading cabling in many cases.
Suitable for
Homes with weak terrestrial DVB-T/DVB-T2 or analog reception
Installations with long coaxial cable runs where signal loss occurs
Single-antenna feeds to a TV or set-top box that need a moderate signal boost
Temporary or permanent installs where a compact amplifier is preferred
Key specifications
Function: terrestrial TV antenna signal amplifier for DVB-T/DVB-T2 and analog
Installation: inline between antenna and receiver
Form factor: compact inline housing compatible with standard coaxial connectors
Purpose: compensates cable attenuation and boosts weak input signals
How to use
Install the amplifier inline on the coaxial cable between the antenna and the television or set-top box, ensuring secure coax connections at both ends. Place the unit as close to the antenna as possible when the aim is to overcome cable loss, or near the receiver when space or access dictates. After connecting, power the amplifier if it requires an external power source and verify signal strength on the receiver. Adjust position or connections if necessary to achieve optimal reception quality.
Usage recommendations
Use the amplifier primarily when signal levels are marginal or cable runs are long. Avoid over-amplifying strong local signals, which can cause receiver overload; if strong signals are present, consider using attenuation or repositioning the amplifier nearer to the receiver. Regularly inspect connectors and cabling to ensure low-loss connections and stable performance.
