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.

I’m pleased with the ærial overall. I did have to fix two separate issues though… 1. Many of the elements were bent, some quite badly. Happily they all bent straight again without any fatigue fracture. 2. Many of the elements were not seated properly in the booms. In one case, a vertical element was touching one on the other boom. I was able to pull the unseated ones out to seat better but I’m not sure how long they’ll stay like this.
