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.

I understand from my inquiry that your stock was low and is why the order was later than anticipated. It have been appreciated if it had communicated to me without me contacting you first, as I had had no information since the initial order confirmation. Having said that once the item was available it was dispatched and arrived within 24 hours and appears to be a quality product, although I have not installed it yet.

Good product and a fair price. A pleasure to deal with friendly company. After researching other products, and other companies, I settled for a suitable serial from Blakes. I have a history of studying aerials and worked in the TV trade some time ago, and the quality of their products impressed me.
