FAQ

Q: What devices typically use this antenna?
A: Remote controls, IoT sensors, industrial transmitters, alarm systems, and any 433MHz wireless device with SMA male ports.

Q: Is it waterproof for outdoor use?
A: Humidity-resistant (5-95% RH), but not submersible. Use a waterproof sleeve if exposed to direct rain.

Q: Can I use this for LoRa or other protocols?
A: Yes! Compatible with LoRa, FSK, OOK, and all 433MHz-based communication protocols.

Q: Why choose 433MHz over 2.4GHz?
A: 433MHz penetrates walls/obstacles better and offers longer range with lower power consumption.

Q: What’s the maximum range?
A: Range depends on transmitter power and environment, but typically 100-500m in urban areas (up to 1km+ line-of-sight).

Q: Does it work with SMA female devices?
A: No – this SMA male antenna requires devices with SMA female jacks.

Q: Is bending the antenna safe?
A: Yes! The flexible rubber design allows repositioning without performance loss.

Q: Is mounting hardware included?
A: No, but its Ø8mm base fits standard antenna holders.
