FAQ

Q: What devices use SMA female connectors?
A: Common in Ubiquiti airMAX gear, MikroTik routers, industrial radios, and CCTV systems.

Q: Can I adjust the antenna length?
A: Yes! Flex between 88.1mm (compact) and 105.4mm (extended) based on space/signal needs.

Q: Is it waterproof?
A: Humidity-resistant (5-95%) but not submersible. Pair with waterproof enclosures for outdoor use.

Q: Will this work with 5GHz WiFi?
A: No – optimized for 2400-2500MHz (2.4GHz band only).

Q: Why choose linear polarization?
A: Maximizes signal efficiency with standard horizontally/vertically mounted devices.

Q: Can I bend the antenna permanently?
A: Yes – the rubber design maintains performance when shaped for directional tuning.

Q: What’s the gain coverage?
A: 2.5dBi omnidirectional – ideal for short-to-medium range applications.

Q: Is it CE/FCC certified?
A: ROHS compliance confirmed. Final device integration determines CE/FCC requirements.
