Blake 4-Way Variable Gain 1-16db Masthead Amplifier with PSU (RED Class-1)

The Blake 4-way Masthead Amplifier is designed to reduce or remove 5G/4G LTE interference and amplify TV frequencies within the 21-48 band (470-694MHz). It has variable 5-20dB gain, low noise figures (<2.5dB typical) and uses F type connectors on both inputs and outputs.

It has variable 1-16dB 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 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.
