SPIDER Automation | 5.8GHz RHCP Skew Planar Wheel FPV Antenna | RP-SMA Male Connector for RC Drone Video Systems
Product Overview & Antenna Design
The SPIDER Automation 5.8GHz RHCP Skew Planar Wheel (SPW) FPV Antenna is designed for circularly polarized analogue video systems used in RC racing drones, quadcopters, FPV goggles and compatible wireless video equipment. Its Skew Planar Wheel antenna geometry is intended to provide a consistent radiation pattern across different antenna orientations, making it suitable for installations where the antenna position may change during operation.
The antenna uses right-hand circular polarization (RHCP) and an RP-SMA male connector. Its flexible cable section can be bent to approximately 90° and retain its adjusted position, helping accommodate equipment with horizontally oriented antenna ports. A reinforced red wire stem adds rigidity, while the protective hard-case enclosure helps preserve the antenna’s physical shape during handling and installation.
Technical Features & RF Characteristics
- 5.8GHz RF Operation: Designed for compatible 5.8GHz FPV analogue video systems.
- RHCP Circular Polarization: Uses right-hand circular polarization and should be paired with compatible RHCP antennas at the other end of the RF link.
- Skew Planar Wheel Geometry: The SPW configuration is designed to maintain a useful radiation pattern across changing antenna orientations.
- Radiation Pattern and VSWR Optimization: The design is intended to optimize radiation characteristics and voltage standing wave ratio (VSWR); numerical test values are not provided.
- Flexible Cable Section: Allows the antenna to be repositioned to suit different mounting orientations and equipment layouts.
- Shape-Retaining Positioning: The flexible section can be bent approximately 90° and retain its adjusted shape.
- Reinforced Wire Stem: The red stem provides additional mechanical rigidity to the antenna assembly.
- Protective Enclosure: The hard-case housing helps protect the antenna structure from accidental bending during handling.
- TX/RX Versatility: The antenna is described as having no dedicated TX or RX version; suitability depends on the connected equipment’s RF connector and polarization requirements.
Connector & Installation Details
The antenna is fitted with an RP-SMA male connector for direct connection to compatible RP-SMA antenna ports. Connector compatibility must be checked carefully because SMA and RP-SMA interfaces are different and are not interchangeable solely on the basis of their external threaded appearance.
The flexible cable section is useful for installations where the antenna port is positioned horizontally or where a straight antenna arrangement would interfere with the equipment housing. It can be adjusted to approximately 90° to improve physical clearance and positioning. Avoid sharp bends, excessive force or repeated unnecessary repositioning.

Installation & Operating Recommendations
For correct RF operation, connect the antenna to equipment with a matching RP-SMA interface and ensure that the connected transmitter or receiver is configured for the appropriate 5.8GHz RHCP antenna system. Proper connector matching, polarization and physical positioning are important considerations when integrating the antenna into an FPV setup.
- Verify Connector Compatibility: Confirm that the equipment uses an RP-SMA antenna port rather than a standard SMA port before installation.
- Match Polarization: Use compatible RHCP antennas at the transmitting and receiving ends of the FPV video link.
- Connect Before Transmitter Operation: Attach the antenna securely before powering an RF transmitter to avoid operating it without a connected antenna.
- Adjust the Cable Carefully: Use the flexible section to obtain the required antenna orientation without applying excessive force or creating sharp bends.
- Maintain Antenna Clearance: Position the antenna away from unnecessary obstructions and nearby conductive structures where practical.
- Protect the Enclosure: Avoid crushing, striking or applying excessive pressure to the protective housing and reinforced stem.
- Check RF System Compatibility: Confirm the operating frequency, connector interface and polarization requirements of the connected FPV equipment before use.
