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.

Fast and easy service with good quality goods

Good intial service, products arrived safely. Downside, found the products about 50% cheaper at another retailer who are reliable and trusted, so not lower quality and the aerial which was recommended for my area is not suitable and the quality of reception is worse then the original aerial.
