FAQ

Q: What devices use this antenna?
A: Routers, IoT sensors, industrial controllers, drones, and any 2.4GHz wireless systems with SMA ports.

Q: Is it waterproof?
A: While humidity-resistant (5-95%), it’s not fully waterproof. Use a protective cover in heavy rain.

Q: Which length should I choose?
A: Short (88.1mm) for tight spaces; Long (105.4mm) for extended range applications.

Q: Does it support 5GHz networks?
A: No, it’s optimized exclusively for 2400-2500MHz (2.4GHz) frequencies.

Q: What’s the warranty period?
A: Typically 1 year, covering manufacturing defects under normal use.

Q: Can I bend the antenna?
A: Yes! The rubber design allows safe bending for optimal positioning.

Q: Why is low VSWR (<2.0) important?
A: Minimizes signal reflection, ensuring maximum power transfer to your device.

Q: Is mounting hardware included?
A: No, but its Ø9.4mm base fits standard antenna mounts/holders.
