The Lectrosonics A8U is a professional UHF whip antenna specifically engineered for wireless microphone and monitoring systems, available in Block 22 covering the 563.200 to 588.700 MHz frequency range. This flexible, durable antenna features a straight BNC connector for universal compatibility with Lectrosonics 200 and 400 series receivers, Octopack multicouplers, and IFB systems, ensuring optimal signal reception in both studio and field applications. Factory-tuned to its designated frequency block, the antenna incorporates a red color-coded tip for immediate visual identification in multi-system setups, following standard resistor value color codes where red indicates Block 22. Designed with practical field use in mind, the A8U provides exceptional installation flexibility with a usable bandwidth of approximately ±50 MHz from the center frequency, allowing reliable operation with antennas from adjacent blocks when necessary. The antenna whip length for Block 22 is precision-cut to 4.48 inches, optimized through network analyzer measurements for maximum RF performance. Constructed from durable RF-rated materials, this rugged yet compact antenna can be mounted directly on receivers or positioned remotely via cable, making it an indispensable component for professional audio professionals requiring reliable UHF signal reception in demanding production environments.
