Sennheiser AD 3700 — Professional Directional Antenna with Integrated Amplifier

In the world of professional wireless systems, key importance lies not only in the quality of transmitters and receivers but also in appropriately selected antenna infrastructure. The Sennheiser AD 3700 is a high-class directional antenna equipped with an integrated AB 3700 antenna amplifier, designed for maximum signal reception effectiveness under the most demanding professional conditions. This advanced directional antenna serves as an indispensable tool for sound engineers, broadcast technicians, and all specialists working with wireless audio systems.

Product Features

The Sennheiser AD 3700 antenna stands out with a range of professional technical parameters that make it the ideal choice for demanding applications. A front-to-back ratio exceeding 14 dB ensures excellent directivity, enabling effective attenuation of signals arriving from the rear of the antenna and minimizing the risk of interference. The integrated AB 3700 antenna amplifier offers signal gain up to 15 dB, allowing for compensation of losses in long coaxial cables and significantly extending the effective reception range. The device is fully compatible with professional Sennheiser wireless receivers from the EM3731, EM3732-II, and EM2000 series, ensuring seamless integration with existing systems.

Professional Capabilities for Your Wireless System

Using a directional antenna in professional wireless systems brings a number of tangible benefits. Signal gain of up to 15 dB allows for a significant increase in reception range without the need to increase transmitter power, which translates to longer battery life in wireless transmitters. The high directivity of the antenna enables precise aiming towards the stage or performance area, while effectively ignoring reflected signals from walls, ceilings, and other surfaces that could cause unwanted interference and multipath effects. The integrated amplifier eliminates the need for external preamplifiers, simplifying system configuration and reducing the number of potential failure points.
