Key Features and Technologies
The Shure UA874US features a log-periodic dipole array, ensuring consistent and reliable signal reception across its 470-900 MHz frequency range. This advanced design provides a wide 3 dB beam width of 70 degrees, allowing for flexible coverage. The antenna also includes third-order overload protection, minimizing interference from nearby high-power signals. A built-in, low-noise signal amplifier compensates for coaxial cable insertion loss, delivering a strong and stable signal to the receiver. These technologies combine to offer superior performance in professional wireless audio systems.
Log-Periodic Dipole Array for Enhanced Reception
The Shure UA874US antenna incorporates a log-periodic dipole array, a sophisticated design that significantly enhances signal reception across its operating frequency range of 470-900 MHz. This array consists of multiple dipole elements arranged in a specific logarithmic pattern, allowing the antenna to achieve a wide bandwidth while maintaining directional properties. The log-periodic design ensures consistent and reliable signal capture, making it particularly effective for professional wireless audio systems requiring stable and high-quality transmission.
One of the key advantages of the log-periodic dipole array is its ability to provide a broad 3 dB beam width of 70 degrees. This wide coverage area offers flexibility in antenna placement and direction, reducing the need for precise alignment while still delivering strong signal reception. Additionally, the array’s directional nature helps minimize interference from signals outside the desired coverage zone, further improving the overall performance of the antenna.
The UA874US also features third-order overload protection, which safeguards the antenna from strong nearby signals that could potentially degrade its performance. This protection ensures that the antenna operates reliably even in environments with high levels of electromagnetic interference. Furthermore, the built-in low-noise signal amplifier compensates for insertion losses in coaxial cables, maintaining a robust and stable signal for the connected receiver.
The durability and compact design of the UA874US are complemented by its versatile mounting options. The antenna can be easily installed on a microphone stand or suspended from a ceiling, making it suitable for a variety of applications, including live performances, installations, and broadcasting. These features, combined with the advanced log-periodic dipole array, make the Shure UA874US an excellent choice for professionals seeking dependable and high-performance wireless audio solutions.
