Product Description
Class 1 1-Way High Gain UHF Masthead Amplifier; 1 Input; 1 Output-27dB
Triple Filtered Reception for Optimal Performance:
4G, 5G, and TETRA Compatibility
Elevate your reception quality with the RED Class 1, Blake 1-Way Variable Fixed Gain 27dB 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 fixed variable 27dB 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.

Good product and a fair price. A pleasure to deal with friendly company. After researching other products, and other companies, I settled for a suitable serial from Blakes. I have a history of studying aerials and worked in the TV trade some time ago, and the quality of their products impressed me.
