Product Description
4-Way UHF Variable Gain Masthead Amplifier; 1 Input; 4 Output-1/16dB
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 (PROMHD14V-PS).
- With equipotential bonding point.

Does the job - excellent.

Response from Blake UK in every respect was very good and the product purchased is excellent. My only criticism is that the package that my omni FM/Dab aerial was sent in could have had more packing material as the carton was damaged in transit with a part of the product sticking out.

Excellent service, both before and after sales.

Good, well made coaxial TV antenna and F-Type satellite socket wall plate. It works well. The packaging could have done with some bubble wrap around the socket though for protection.

Super quick service. Please use less tape on the mast next time :-)

I already knew Blake from years ago. They are a quality vendor. The first BLA-LP56K was damaged by the courier in transit and they replaced it straightaway no quibbles the next day. This worked a treat in the loft with a masthead amp (have power in big loft). C/N : 30dB, sig: 100%, quality:100%: BER: 0.0. The aerial was connected into an IRS as the rooftop aerial had failed probably due to water ingress in the balun and I was quoted from £250 - £450 for a replacement outside antenna, probably because we have a very tall house/outside installation.Why bother when you know a log in the loft is going to work 11 miles from a 200kW station. As Blake say this is suitable for medium or strong signal areas but the addition of the masthead boosts the signal nicely for all round the house distribution.
