SPACETRONIK ZASARF Adjustable Antenna Power Supply with F-Type Socket DC 2-12V/100mA

Weak TV signal from your terrestrial antenna often comes down to insufficient power reaching the amplifier. The SPACETRONIK ZASARF solves this by delivering adjustable DC voltage directly through the coaxial line, letting you fine-tune the gain for the clearest possible picture without climbing onto the roof.

Who is it for

Home users with active indoor or outdoor DVB-T/T2 antennas, installers setting up signal distribution in apartments, and anyone who needs to compensate for long cable runs or splitter losses. If your antenna has a built-in preamplifier, this compact power supply is the missing link between your wall socket and reliable reception.

Main features

• Adjustable output voltage from 2 V to 12 V DC via a potentiometer – match the exact requirement of your antenna amplifier.
• F-type female output connector feeds power through the coaxial cable while passing the RF signal from 5 to 862 MHz with less than 1 dB insertion loss.
• Integrated Europlug (Type C) connects directly to any 230 V / 50 Hz mains socket – no separate power brick needed.
• Short-circuit protection and LED power indicator ensure safe operation and instant status check.
• Compact plastic housing with mounting slots for discreet installation behind a TV or in a distribution box.

Tips

Start with the lowest voltage setting and increase gradually until your signal quality peaks – too much voltage can overdrive the amplifier and cause interference. For best results, place the power supply close to the antenna and use high-quality RG6 coaxial cable with proper F-connectors.
