Product Description
RED Class 1, Blake 2-Way Variable Gain 5-20dB Masthead Amplifier (470-694MHz)
Triple Filtered Reception for Optimal Performance:
4G, 5G, and TETRA Compatibility
Elevate your reception quality with the RED Class 1, Blake 2-Way Variable Gain 5-20dB Masthead Amplifier. This CE/UKCA compliant amplifier offers exceptional performance, incorporating advanced 5G/4G LTE filtering and amplification for TV frequencies within the 21-48 band (470-694MHz). With its variable 5-20dB gain and low noise figures (<2.5dB typical), it ensures optimal signal strength and clarity. The amplifier features F-type connectors on both inputs and outputs for easy connectivity.
Designed to reduce interference from 5G/4G LTE signals, the amplifier exhibits excellent filter characteristics with >30dB suppression for frequencies below 400MHz. It is also compliant with Class 1 EN 303 354 standards for effective filtering of 5G frequencies. Additionally, the amplifier filters TETRA signals below 470MHz.
The amplifier's thoughtfully engineered design allows for convenient access. The case opens to a full 90 degrees, providing easy access to the F connectors, while the shielded amplifier casing swings out to 45 degrees. The casing includes an LED indicator to confirm power reception.
With a robust and water-resistant construction, the amplifier features seal-protected cable entry points to prevent moisture and insects from compromising its performance. The case securely closes with a satisfying "solid click" and includes an optional security screw for added protection.
Designed for linearity, the amplifier effectively handles strong local signals without compromising performance.
