SPIDER Automation | 5.8GHz RHCP Cloud Spirit FPV Antenna Pair | 3-Lobe TXA & 4-Lobe RXA for RC Drone Video Systems
Description
The SPIDER Automation 5.8GHz RHCP Cloud Spirit Antenna Set is a pair of circularly polarized omnidirectional antennas designed for compatible FPV wireless video systems. The set contains two different antenna configurations: a three-lobe TXA antenna for video transmission and a four-lobe RXA antenna for video reception. This arrangement provides dedicated antenna elements for the transmitter and receiver sides of a compatible FPV link.
Both antennas use Right-Hand Circular Polarization (RHCP) and are designed for operation in the 5.8GHz FPV frequency band. Their clover-style antenna elements are enclosed within RF-transparent protective domes, providing physical protection while allowing radio-frequency signals to pass through. The dome-enclosed construction also gives the antennas a compact, finished appearance compared with exposed traditional cloverleaf antenna elements.
Each antenna features an RP-SMA male connector and a bendable construction for convenient installation and positioning. The specified antenna gain is 3dBi, with a standing wave ratio (SWR) below 1.5. The pair is intended for compatible 5.8GHz FPV transmitters, receivers and RC drone video systems that support the specified connector and polarization configuration.
Technical Features & Design Characteristics
- Dedicated TX and RX Antennas: The set includes separate antenna configurations for the transmitter and receiver sides of an FPV video system.
- Three-Lobe TXA Configuration: The transmitter antenna uses a three-lobe circularly polarized omnidirectional design.
- Four-Lobe RXA Configuration: The receiver antenna uses a four-lobe circularly polarized omnidirectional design.
- 5.8GHz Frequency Band: Designed for compatible 5.8GHz FPV wireless video equipment.
- RHCP Circular Polarization: Both antennas use Right-Hand Circular Polarization to support matching RHCP antenna configurations.
- Omnidirectional Antenna Design: The TXA and RXA configurations are described as omnidirectional, supporting coverage around the antenna rather than requiring a single directional alignment.
- RF-Transparent Protective Housing: The dome enclosure protects the internal antenna elements while permitting RF signal transmission and reception.
- Bendable Construction: Allows the antenna assemblies to be positioned according to equipment layout and mounting requirements.
- RP-SMA Male Interface: Both antennas use RP-SMA male connectors for compatible RF ports.
- Specified 3dBi Gain: Provides the stated gain specification for the antenna set.
- Low SWR Specification: The stated SWR of less than 1.5 indicates the specified impedance-matching performance.
TXA & RXA Antenna Configuration
The two antennas in this set have different lobe configurations and are intended for different positions in the FPV video link. They should be identified and installed according to their TXA and RXA designations.
| Parameter | TXA Antenna | RXA Antenna |
|---|---|---|
| Application | Transmitter | Receiver |
| Lobe Configuration | Three lobes | Four lobes |
| Polarization | RHCP | RHCP |
| Radiation Pattern | Omnidirectional | Omnidirectional |
| Connector | RP-SMA Male | RP-SMA Male |
Protective Dome & Installation Design
The clover-style antenna elements are enclosed inside RF-transparent protective domes. This construction helps reduce direct physical contact with the internal antenna elements during handling and installation. The protective housing also helps maintain the antenna assembly’s form compared with exposed antenna structures.
The bendable construction allows the antennas to be positioned according to the available mounting space and orientation of the connected equipment. During installation, the antenna should be positioned without excessive mechanical force on the cable, connector or protective enclosure.

Connection & Operating Recommendations
Correct antenna selection, polarization matching and connector compatibility are important for integrating this pair into an FPV video system. Identify the TXA and RXA antennas before installation and connect each to its corresponding transmitter or receiver equipment.
- Identify TXA and RXA: Install the three-lobe TXA antenna at the transmitter and the four-lobe RXA antenna at the receiver, following the intended configuration.
- Verify RP-SMA Compatibility: Confirm that both connected devices have matching RP-SMA female antenna ports. RP-SMA and standard SMA are different connector interfaces.
- Match Polarization: Use compatible RHCP antennas throughout the FPV link to maintain polarization matching.
- Confirm Frequency Compatibility: Use with equipment designed for the 5.8GHz frequency band.
- Position the Antennas Properly: Arrange the antennas to avoid unnecessary obstruction by conductive structures and equipment components.
- Handle the Protective Domes Carefully: Avoid crushing or applying excessive force to the housings during installation and maintenance.
- Avoid Mechanical Stress: Do not forcefully bend or twist the antenna assemblies, connectors or cable sections.
