OPTICUM W-20 In-Line Antenna Amplifier 20dB

The OPTICUM W-20 is a high-performance in-line antenna amplifier designed to boost weak terrestrial TV and radio signals. With a gain of 20 dB, it compensates for signal loss in long cable runs or splitter installations, ensuring reliable reception of DVB-T/T2, FM, and DAB+ broadcasts. The amplifier features a compact, shielded metal housing and is powered via phantom power through the coaxial cable, eliminating the need for a separate power outlet at the antenna location.

Advantages

Easy to install directly in the antenna cable line. The 20 dB gain effectively strengthens signals without introducing excessive noise (noise figure < 3.5 dB). Supports a wide frequency range from 47 to 862 MHz, covering VHF, UHF, FM, and DAB+ bands. The F-type connectors ensure secure and low-loss connections. Phantom power supply (5-12 V DC) simplifies installation by using the same coaxial cable for both signal and power.

Suitable for

• Improving weak terrestrial TV signals in areas with poor reception
• Compensating for signal loss due to long cable runs or multiple splitters
• Enhancing FM and DAB+ radio signals
• Indoor and outdoor use (operating temperature -20 to +50 °C)
