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.
- With equipotential bonding point.

Trouble-free order and rapid delivery. I bought this amplifier because the existing one lacked gain, the Blake amp. means I can now get HD channels. Not only that but the in-built filtering means I can now transmit amateur radio on 144 and 432 MHz without causing TV problems. Couldn't be better! Wife impressed!
