4 way UHF Masthead Amplifier; Variable Gain 1-16dB, Power Any Output


This range of high-performance low-noise preamplifiers and multi-way mastheads includes both fixed and variable gain versions. Selected models can be powered at 5 to 12 volts, allowing powering directly from certain digital terrestrial set-top boxes or IDTVs which can provide 5 V output at the aerial socket.




  • Fully-screened amplifier modules in robust diecast enclosures. Strong cast-in 'F' connectors.
  • Free-draining moulded outer enclosures give easy access and cannot trap water.
  • Low noise figures and well-filtered inputs. Sharp cut off below 400 MHz, helps avoid interference problems from nearby transmitters: CB, PMR, TETRA, HF & VHF amateur radio, etc.
  • Variable gain models have interstage control to maintain good noise figure at reduced gain.
  • All multi-way amplifiers can be powered via any output.
  • Also available complete with power supply (proPSU11F).
  • With equipotential bonding point.
