Advantages for LoRa Projects

• Extends wireless communication range for fewer gateways and repeaters
• Improves packet reliability and reduces retransmissions
• Easy installation allows rapid prototyping and deployment
• Robust performance in both indoor and outdoor environments when properly installed

Installation and Safety Notes

• Ensure the antenna is securely connected to the RA-02 module before powering the RF transmitter
• Never operate the transmitter for extended periods without an antenna attached, as this may damage the RF output stage
• For outdoor installations use appropriate enclosures, sealing, and grounding to protect against weather and static
• Place the antenna clear of large metal surfaces and other RF sources for best performance

Compatibility and Integration Tips

This antenna is designed for direct compatibility with LoRa RA-02 modules and other 433 MHz radio modules that use the same antenna interface and 50 ohm impedance. For optimal results, match impedance and minimize feedline loss by using short, high-quality coaxial connections and proper connectors.

Ordering Information

When ordering, verify the connector type and physical fit with your RA-02 module and enclosure. Typical color is black and the product ships as a single external antenna unit unless otherwise specified.
