Product Description

RED Class 1, Blake 4-Way Variable Gain 1-16dB 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 4-Way Variable Gain 1-16dB 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 1-16dB 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.

Installer-Friendly Design:

  • 90° Wide Opening Door for easy access.
  • Optional Securing Screw for added stability.
  • Heavy-Duty UV Stabilized Cable Tie for secure installation.
  • Dual LED Indicators for advanced short circuit protection.
  • Foam Seal Cable Entry Glands to safeguard against external elements.
  • Power LED on Amplifier for visual confirmation of power status.
  • 45° Swivel and Click Amp for flexible positioning.
  • Robust Wall Mountable Lugs for secure installation.
  • Available in 2, 4, and 8 outputs for diverse setup requirements.
  • Low Noise Figures <2.2dB for superior signal quality.
  • F-Type Connectors for reliable connections.
  • Equipotential Bonding Point/Earthing Tag for safety compliance.

Early Feedback from Installers:

I understand from my inquiry that your stock was low and is why the order was later than anticipated. It have been appreciated if it had communicated to me without me contacting you first, as I had had no information since the initial order confirmation. Having said that once the item was available it was dispatched and arrived within 24 hours and appears to be a quality product, although I have not installed it yet.

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.
