PRODUCT DETAILS
The Blake BLAMHD11H is a 1-Way Variable Fixed Gain 27dB Masthead Amplifier which 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.
Features:
- 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.

Waltham's ERP (Effective Radiated Power): Quite strong (up to 100–170 kW for main multiplexes), meaning a good quality aerial usually performs well without excessive amplification, unless the path is obstructed or cable loss is significant.
A 27dB masthead amplifier might be too strong at 35 miles from Waltham—unless your signal is very poor or your cable runs are long. Try a lower gain first, or make sure to test carefully and consider adding an attenuator if needed.
