Description

The Holybro 433MHz Antenna is engineered for robust wireless communication in the 433MHz Industrial, Scientific, and Medical (ISM) band. Its 2dBi gain provides a balanced radiation pattern, offering improved signal range and reliability for telemetry data streams, RC control links, and low-bandwidth data transfer without the bulk of higher-gain directional antennas.

Built with a durable whip design and an RP-SMA connector, this antenna ensures a secure physical and electrical connection to compatible RF transmitters and receivers. Its compact form factor and low weight make it an ideal choice for airborne applications on drones, where minimizing aerodynamic drag and payload is critical, as well as for ground station setups requiring stable, long-range connectivity.

Key Features

  • Frequency-tuned for optimal performance in the 433MHz ISM band.
  • 2dBi omnidirectional gain provides a reliable communication bubble.
  • Standard RP-SMA (Reverse Polarity SMA) connector ensures wide compatibility.
  • Lightweight and low-profile whip design minimizes impact on flight dynamics.
  • Rugged construction withstands vibrations and environmental exposure typical in UAV operations.
  • Enhances signal-to-noise ratio for clearer telemetry and control data.
  • Simple plug-and-play installation with no tuning required.

Applications

  • Long-range telemetry links for ArduPilot or PX4-based autonomous drones.
  • Control link antenna for 433MHz RF systems like Holybro SiK Telemetry Radios.
  • Ground station antenna for receiving drone telemetry and mission data.
  • Low-bandwidth data transfer for UAV payloads operating in the 433MHz band.
  • FPV system backup or secondary communication channel on long-endurance platforms.

Frequently Asked Questions

What is the connector type on this Holybro 433MHz antenna?

This antenna features a standard RP-SMA (Reverse Polarity SubMiniature version A) male connector. It is designed to mate with female RP-SMA ports commonly found on many 433MHz telemetry radios and RF modules, such as those from Holybro and other manufacturers in the UAV ecosystem.

What is the typical range and use case for this 433MHz antenna?

With its 2dBi omnidirectional gain, this antenna is optimized for medium to long-range applications in the 433MHz ISM band. Typical uses include extending the range of telemetry links for flight controllers like Pixhawk, serving as a control antenna for RC systems, or providing a reliable low-bandwidth data link for UAV payloads, often achieving several kilometers in open areas.

Is this antenna compatible with my 433MHz telemetry radio from a different brand?

Yes, compatibility is primarily determined by the connector type and operating frequency. If your 433MHz radio module has a female RP-SMA port, this antenna will be mechanically and electrically compatible. Always verify that your radio's output power and the antenna's power handling are suitable for your intended range and regulatory requirements.
