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.

Came across Blake through a google search for a decent DAB/FM aerial. Good reviews, decent website. I purchased one, it arrived quickly and with the decent instructions, I got it installed and it's working great. All good. Would use again, recommended.

Ive moved into a new build property and wanted to fit a TV aerial in my loft. After searching the net looking for advice on aerials I found Blake’s website. I put in my postcode and not only told what aerial I needed it also told me the transmitter I need to aim at. Prices were very reasonable and delivery was very quick. Was kept very well informed on my orders progress. Very impressed. Would definitely recommend to anyone 👍🏻

I used the online customer support system used by Blake UK for advice regarding my intended installation and got very quick and helpful advice on what would suit me best….this was honest advice as I was thinking of purchasing more expensive items that would be unnecessary and also possibly even detrimental to my intended installation. My order was received very quickly and although there had been a small mistake regarding the length of cable I had ordered this was immediately rectified by Blake UK again using their online messaging system. Personally I cannot fault Blake UK and would be very happy to recommend them to anyone, a very helpful and professional business, thank you.
