Product Description
RED Class 1, Blake 4-Way High Variable Gain 12-27dB Masthead Amplifier (470-694MHz)
For the best reception with triple filtering:
4G, 5G, and TETRA Compatibility
One of the best designed, CE/UKCA, Class 1 RED compliant, 4G/5G filtered masthead distribution amplifiers on the market.
Designed to remove or reduce 5G/4G LTE interference and amplify TV frequencies within the 21-48 band (470-694MHz). It has variable 12-27dB gain, low noise figures (<2.5dB typical) and uses F-type connectors on both inputs and outputs.
The filter characteristics are >30dB for frequencies <400MHz and Class 1 EN 303 354 compliant for 5G filtered frequencies. The amplifier also filters TETRA signals below 470MHz.
The case opens to a full 90 degrees and the shielded amplifier casing also swings out to 45 degrees, ensuring quick and easy access to the F-type connectors. The amplifier has an LED on the casing to confirm it is receiving power.
The case is further water resistant by a seal on the cable entry points, to preventing both moisture and insects. The case securely closes with a “solid click” but there is also an additional security screw fitted should it be needed.
The amplifier is designed with linearity in mind which allows the ability to handle strong local signals.
To ensure the lowest noise possible, we use a linear power supply rated at 100mA within the kit. Current consumption of this MHA is <50mA.
This also has dual-coloured LED to display short circuit issues running from green (normal) to red (short). The power supply also has infinite short circuit protection to stop damage to the unit.
Designed with the installer in mind:
- 90° Wide Opening door that clicks open/shut.
- Securing Screw(optional).
- Heavy Duty UV Stabilised Cable Tie.
- Dual LED – Advanced Short Circuit Protection.
- Foam Seal Cable Entry Glands.
- Power LED on Amplifier.
- 45° Swivel and Click Amp.
- Robust Wall Mountable Lugs.
- Low Noise Figures <2.2dB.
- F-Type Connectors.
- Equipotential bonding point/earthing tag.
Here’s some early feedback from installers:
“The quality is superb – you can tell that immediately from the robust housing.”
“I’d say it’s a nicely designed product with some neat features like foam seal cable entry – you’ve clearly been listening to installers.”
“Great to finally have a masthead that I can fit compression connectors into. Nice work.”
This is a new expanding range, which will become a family of products.

Great performance when have weak signal from K type transmitter. Wish we had it a few years ago but the high gain one fitted by local TV aerial company was badly affected by weather. This one works in recent bad weather fine

Arial's would seem they are not just aerial's! Aerials from Blake UK are well made and robust, it was well packaged and ease of purchase was good and well protected for transit. Highly recommend 5 star rating.

Simple and reliable ordering system. My antenna mast & bits arrived on time and in good condition. The driver even took the mast to my garage. This order is for an amateur radio VHF/UHF antenna M7GIM.
