FAQ
Q: What is the difference between Waveguide Twist and waveguide rotary joint?
A: Waveguide Twist only rotates the polarization direction and has no mechanical rotating parts. It is suitable for fixed polarization adjustment. The rotary joint supports mechanical rotation and is used for dynamic polarization adjustment, but it has higher insertion loss.
Q: Does Waveguide Twist support high humidity environments?
A: Yes. The industrial-grade model adopts an IP67 protection design and can operate stably in an environment with a relative humidity of 95%. It also offers a salt spray resistant version for Marine applications.
Q: How to choose the frequency band of Waveguide Twist?
A: Select the corresponding waveguide size based on the system's operating frequency, or contact us to customize a cross-band model.
