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.
- With equipotential bonding point.

Very courteous and helpful in dealing with my order error. A decent antenna delivered very quickly and I now have fm radio with a full strength signal.

I had a bit of a struggle with their online ordering, I managed to raise an order as "collection" rather than delivery by courier. However Blake's went out of their way to fix the problem. Otherwise their on-line service produces a good transaction trail.
