Product Description
2-Way UHF Medium Gain Masthead Amplifier; 1 Input; 2 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 (PROMHD12M-PS).
- With equipotential bonding point.
| Product Code | Ways | Gain | NF | Max Input | Power Requirement | Typical Applications |
| PROMHD12M | 2 | 10dB | 1.8dB | 78dBV | 5 - 12V, 25 mA | 2-way D/A margin raiser |
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

All Arrials I purchased were installed at BBC Radio Gloucester with great results Will be purchasing more soon Thank you Blake Team DAB @ FM

I used the online customer support system used by Blake UK for advice regarding my intended installation and got very quick and helpful advice on what would suit me best….this was honest advice as I was thinking of purchasing more expensive items that would be unnecessary and also possibly even detrimental to my intended installation. My order was received very quickly and although there had been a small mistake regarding the length of cable I had ordered this was immediately rectified by Blake UK again using their online messaging system. Personally I cannot fault Blake UK and would be very happy to recommend them to anyone, a very helpful and professional business, thank you.
