Product Description
4-Way UHF Medium Gain Masthead Amplifier; 1 Input; 4 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 (PROMHD14M-PS).
- With equipotential bonding point.

Fast and easy service with good quality goods

Good intial service, products arrived safely. Downside, found the products about 50% cheaper at another retailer who are reliable and trusted, so not lower quality and the aerial which was recommended for my area is not suitable and the quality of reception is worse then the original aerial.

TV aerial bought from Blake was excellent quality at a reasonable price after asking a relative in the industry who he’d recommend. Website was easy to use and offered the facility to find the aerial type (K) for my postcode, the nearest transmitter and its heading from my property. Aerial itself is lightweight yet robust and picture quality is superb. Instructions are good. Can’t see how this aerial will suffer from water ingress like my cheap previous aerial. Do it right do it once! Would highly recommend.

I needed a custom size aerial tube bent. Blake were quick off the mark to give a quote (very reasonable) and after paying, I had the finished item a few days later by courier. Excellent service, and the finished tube was accurately bent to the drawing.
