Product Description
4-Way UHF Variable Gain Masthead Amplifier; 1 Input; 4 Output-1/16dB and PROPSU11F Power Supply
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.

Had to ring to see why I hadn't received my order, was told one item was out of stock, said they didn't know when they would receive the item but that same day it was sent to the courier, then still took another four days before I received my package,very poor packaging,hard to get into, one pole badly scratched and the other has a sticker on it that I cannot remove.
