Shure HA-4540 Tour Grade Helical Antenna

The PWS TS Helical Antenna offers unparalleled drop-out free RF performance for IEM, wireless mics and intercoms. Helical Antennas provide greater bandwidth, longer range, greater reliability and more flexibility than other antennas. Unlike traditional whip and or fin antennas which transmit and receive signals in a single polarization, the circular motion of the RF field emitted by a helical antenna distributes the signal through all possible polarization, greatly reducing the risk of drop-outs. The high gain ensures the strongest possible signal.
