Product Description
2-Way UHF Medium Gain Masthead Amplifier; 1 Input; 2 Output-10dB
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 (PROMHD12M-PS).
- With equipotential bonding point.

Hi service was good but i think you should have the brackets hot dip galvanised and charge a bit more for them because paint does not last very long these days other than that sturday bracket

There was an issue with delivery - the couriers lost my 10 foot mast pole! However, I cannot fault Blake in their attempts to put things right. They immediately sent out another pole as a replacement, which has just been received. Things in life can always go wrong. It is how a company responds to problems which show if they are a good company. Blake - you certainly showed that you are customer focussed. If I ever decide to put another weather station on the side of my house, you will be the first port of call for the needed equipment.

I ordered a 1 in 2 out Hdmi switch but it was out of stock and rather than getting me to wait until it was in stock Blake UK sent a more expensive 1 in 4 out Hdmi switch at no extra charge. It was also delivered very quickly. I would there rate Blake UK ver highly - hence the 5 stars.
All good
