Product Description

1-Way UHF High Gain Masthead Amplifier; 1 Input; 1 Output-27dB and PROPSU11F Power Supply

Features:

  • This range of high-performance low-noise pre-amplifiers 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 5V output at the aerial socket.
  • Fully-screened amplifier modules in robust die-cast 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 and VHF amateur radio, etc.
  • Variable gain models have inter-stage control to maintain good noise figure at reduced gain.
  • All multi-way amplifiers can be powered via any output.
  • With equipotential bonding point.

Good product and a fair price. A pleasure to deal with friendly company. After researching other products, and other companies, I settled for a suitable serial from Blakes. I have a history of studying aerials and worked in the TV trade some time ago, and the quality of their products impressed me.
