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.

- 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.

First class website and easy to navigate when buying items from Blake UK. Was emailed every step for reassurance regarding my on-line order for a stress free purchase. Will definitely be doing another on-line order from Blake UK regarding a TV ariel along with a loft bracket as I will be buying a loft Ariel in a few months time for my home. 💯% satisfied with my order 👍

I’m pleased with the ærial overall. I did have to fix two separate issues though… 1. Many of the elements were bent, some quite badly. Happily they all bent straight again without any fatigue fracture. 2. Many of the elements were not seated properly in the booms. In one case, a vertical element was touching one on the other boom. I was able to pull the unseated ones out to seat better but I’m not sure how long they’ll stay like this.

This is my second review for this same product. I bought a Twin Coax Surface Mount Switch Outlet Box, but could only get it to work if I physically held the aerial in place, so left a one star review. I quickly received an email from Chloe offering a couple of solutions to the problem, so I decided on a new switch with a soldered coax cable, which I'm pleased to say works perfectly. After receiving such a friendly and efficient service I have definitely changed my mind about Blake-uk.com and would not hesitate to recommend them.

I was looking for some roof hardware and found what I needed at Blake at a competitive price. I'm glad I bought through them because the transaction was simple and the delivery lightning fast. Received what I ordered on time and happy with the quality. So definitely will use them again.
