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.

First class website and easy to navigate when buying items from Blake UK. Was emailed every step for reassurance regarding my on-line order for a stress free purchase. Will definitely be doing another on-line order from Blake UK regarding a TV ariel along with a loft bracket as I will be buying a loft Ariel in a few months time for my home. 💯% satisfied with my order 👍

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.

Blake UK provide an outstanding service. We recently moved into a new home and the existing TV signal reception was limited to a few flaky channels. I have never faced an issue like this before and wasn't sure if our smart TV, cabling or aerial were at fault. Rhys and the comprehensive information on the Blake UK website (including directional data for my nearest transmitter) resolved the problem very fast. A new and specific aerial, mast pole, clamps and instructions were efficiently dispatched and received the following day. I now have 844 channels! I should mention that during the installation the option to check signal strength and clarity on a Sony Bravia TV can be found in the 'Settings / Help / Signal Diagnostics' menu section.

I was looking for some roof hardware and found what I needed at Blake at a competitive price. I'm glad I bought through them because the transaction was simple and the delivery lightning fast. Received what I ordered on time and happy with the quality. So definitely will use them again.
