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.

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.
