Shure HA-8091 Domed Helical Antenna - 460-900 MegaHertz

For venues and installations where site line appearance is a priority, the PWS Domed Helical Antenna features the same circular polarization as the original PWS Helical but in a sealed enclosure with a more compact profile. PWS Helical Antennas have become the industry standard for multi-channel wireless microphone, in-ear, and intercom systems thanks in part to their unique characteristics, lending to extreme flexibility of use. With an inherent boost in gain, greater bandwidth, and drop-out free polarization, PWS Helical Antennas truly outshine the performance of traditional antenna designs. Inconspicuous and robust, the PWS Domed Helical Antenna is a great choice when the requirements of aesthetics and function can’t be compromised.

Features:

• Ideal for use in large-scale events, where it may be improbable to control the orientation of sending and receiving ends of the wireless system
• Unlike traditional whip antennas which transmit and receive signals in a single polarization, the circular motion of the RF field emitted by the helical antenna distributes the signal through all possible polarization, greatly reducing the risk of dropouts
• High gain ensures strong signal
• RF energy rotates through all 360 degrees of polarization, providing clear reception in the artist's ears and in the wireless mic's receiver no matter how they may move about on stage
• Use as a transmitting antenna or a receiving antenna
• Dual mounting adapter supports 5/8"-27 and 3/8"-16 standards
