Product Description

1-Way UHF Medium Gain Masthead Amplifier; 1 Input; 1 Output-16dB

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.
  • Also available complete with power supply PROPSU11F (PROMHD11M-PS).
  • With equipotential bonding point.

Blake UK Ltd I was pleasantly surprised by this Sheffield Company. They're easy to order from,in my case online and email and text communication as I lip read, the item was ready to collect as per the order agreed. Far better service than Amazon for the said item still on back order with Amozon with a delivery date as far away as November 2024. I think it's probably come full circle, and shopping experience might be coming back, and with a company like Blake UK...I'd happily recommend them over and over. Well done ?

A REFRESHING CHANGE. Needed more info on an item. Fast response, friendly, informed, clear, offered alternative suggestion.... First experience with "Blake". Couldn't have asked for more. Thanks a lot Blake. I'm buying.
