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 intial service, products arrived safely. Downside, found the products about 50% cheaper at another retailer who are reliable and trusted, so not lower quality and the aerial which was recommended for my area is not suitable and the quality of reception is worse then the original aerial.

I needed a custom size aerial tube bent. Blake were quick off the mark to give a quote (very reasonable) and after paying, I had the finished item a few days later by courier. Excellent service, and the finished tube was accurately bent to the drawing.
