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.
Technical Information:
| Product Code | Ways | Gain | NF | Max Input | Power Requirement | Typical Applications |
| PROMHD14V | 4 | 1 - 16dB | 2.2dB | 80dBV | 12V, 50 mA | Universal 4-way D/A |
The maximum output level per multiplex is per the table in dBV when there are eight equal level multiplexes. If the number of multiplexes to be carried is not eight please refer to our Mux guide.

I researched for many TV aerials and my friend who was ex aerial rigger recommended me Blake aerials as you can’t go wrong with them that was his words and it was true

Ok until Blake sold me an item they didn't have in stock ...

Blake UK Ltd I was pleasantly surprised by this Sheffield Company. They're easy to order from,in my case online and email and text communication as I lip read, the item was ready to collect as per the order agreed. Far better service than Amazon for the said item still on back order with Amozon with a delivery date as far away as November 2024. I think it's probably come full circle, and shopping experience might be coming back, and with a company like Blake UK...I'd happily recommend them over and over. Well done 👏

A REFRESHING CHANGE. Needed more info on an item. Fast response, friendly, informed, clear, offered alternative suggestion.... First experience with "Blake". Couldn't have asked for more. Thanks a lot Blake. I'm buying.
