The Shure Helical Antenna is part of a new generation of antennas that provide greater bandwidth, longer range gain and more flexibility in wireless communications. Unlike the traditional whip antenna, which transmits or receives signals in a single polarization, the helical antenna distributes signals multi-dimensionally. The circular motion of the RF field emitted by the helical antenna reduces the risk of drop-outs and guarantees the strongest possible signal for receiving and transmitting.
This antenna is particularly useful in large-scale events, where it is virtually impossible to control the orientation of both the sending and receiving ends of communication.
It can be used in a couple of different ways – as an In Ear Monitor transmitter antenna or with a receiver for wireless microphones.
Typically, performing artists wear a receiver that includes a ¼ wave whip antenna. Any movement can result in a lower quality transmission. With the helical antenna, radio frequency transmits through 360 degrees polarization, providing crystal clear reception in the artists’ ear no matter how much they move or where they go on the stage.
The same applies when an artist is using a wireless microphone. A helical antenna can be used with the receiver for greater performance no matter how much the handheld microphone is moved around.
