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
