I’d like to thank Nathan and the team at Wendy’s Broadcadst for all their help. They have been supplying me with custom cables, made to the highest standard over many year. The low profile connectors are hard to find, yet they normally ship the finished leads the day after ordering, often to studios or locations where I am filming and I’ve never had to ask for any adjustments or corrections; They are right first time, despite my requiring some unusual bespoke wiring. I’ve also benefited from real world advice about products and fault finding. Wendy’s Broadcast have made location sound far less stressful.

£695.00 ex vat 
£834.00 inc vat
The UHF AWPB-1W amplifier delivers up to 1W output power with 12 dB small-signal gain, excellent gain flatness, wide dynamic range, and a low Noise Figure. It is designed to boost low-power radio microphone transmitters to a full 1W for applications such as sports audio links, car-to-car recording, IEM TX range extension, and similar long-range needs.
A custom-tuned, highly selective band-pass filter in the output stage sets the operating frequency range and effectively suppresses 2nd and 3rd harmonics.
Gain can be adjusted in 0.5 dB steps via the intuitive OLED interface. A real-time DC voltmeter monitors input voltage continuously, and the Lock Menu prevents unintended changes to user settings.The booster is compatible with any UHF wireless transmitter operating within the same tuning range, including Digital, Hybrid FM and Analog FM systems. Its wide input dynamic range accepts transmitter power levels from 0 dBm (1 mW) up to +18 dBm (63 mW).The AWPB-1W features a compact, custom-designed enclosure with an integrated heat sink and advanced PCB thermal design to minimize heat build-up. The CNC-machined aluminium housing is black-anodized and laser-marked, providing durability and reliable performance in demanding environments.
