SPIDER Automation | 5.8GHz 2.8dBi RHCP Long Lollipop FPV Antenna | Omnidirectional Antenna for RC Drones
Product Overview & Antenna Design
The SPIDER Automation 5.8GHz 2.8dBi RHCP Long Lollipop FPV Antenna is designed for compatible 5.8GHz FPV video transmission and reception systems used in racing drones, quadcopters and other radio-controlled aircraft. Its omnidirectional radiation design provides coverage around the antenna, making it suitable for aircraft installations where the relative orientation between the transmitting and receiving antennas changes during operation.
The antenna uses Right-Hand Circular Polarization (RHCP), a polarization configuration commonly used in FPV radio-frequency systems. Its long-format 150mm antenna assembly is connected through an integrated 120cm cable terminating in an RP-SMA male plug connector. This cable arrangement provides flexibility when positioning the antenna away from the transmitter or receiver, subject to the mounting layout and cable-routing requirements.
Technical Features & Performance Characteristics
- 5.8GHz RF Operation: Designed for compatible 5.8GHz FPV video systems, allowing integration with equipment operating in the corresponding frequency band.
- 2.8dBi Stated Antenna Gain: Provides the specified gain value for RF system selection and antenna configuration planning.
- RHCP Circular Polarization: Uses right-hand circular polarization to support an appropriately matched circularly polarized FPV antenna link.
- Omnidirectional Radiation Pattern: Designed to provide coverage around the antenna rather than a concentrated directional beam, supporting changing aircraft orientations.
- Radiation Efficiency Greater Than 50%: The specified efficiency provides a reference characteristic for evaluating the antenna’s RF performance.
- RP-SMA Male Connection: Terminates in an RP-SMA male plug for connection to compatible antenna interfaces.
- Extended Integrated Cable: The 120cm cable provides additional positioning flexibility when the antenna needs to be mounted away from the connected RF equipment.
- Long-Format Antenna Assembly: The stated 150mm height distinguishes this version from shorter compact Lollipop antenna configurations.
- Low-Weight Assembly: The 11g stated weight is relevant when considering antenna placement and overall aircraft payload.
- Broad Temperature Operating Range: The specified operating temperature range is -40°C to 85°C.
RF Connector, Cable & Polarization Details
The antenna is supplied with an RP-SMA male plug connector and an integrated 120cm cable. Before installation, verify that the connected FPV transmitter or receiver has the corresponding RP-SMA female interface. RP-SMA and standard SMA connectors are mechanically similar but have different centre-contact configurations, so they should not be treated as interchangeable.
The antenna uses RHCP polarization. For the intended circularly polarized FPV link, select a receiving or transmitting antenna with compatible RHCP polarization at the opposite end. Cable routing should avoid sharp bends, crushing and unnecessary mechanical strain, particularly near the antenna feed and connector.
Applications
This long-format antenna is suitable for compatible 5.8GHz FPV installations where an omnidirectional RHCP antenna and an extended cable connection are required.
- FPV Racing Drones: For compatible 5.8GHz video systems installed on racing quadcopters.
- FPV Freestyle Quadcopters: For freestyle aircraft requiring circularly polarized omnidirectional antenna coverage.
- RC Multirotor Aircraft: For compatible multirotor platforms equipped with 5.8GHz FPV video equipment.
- Long-Format Antenna Installations: For configurations requiring the stated 150mm antenna assembly.
- Remote Antenna Positioning: For installations where the integrated 120cm cable allows the antenna to be positioned away from the connected RF equipment.
- Analogue FPV Video Links: For compatible 5.8GHz analogue FPV transmitters and receivers.
- Custom FPV Builds: For custom aircraft configurations using a compatible RP-SMA interface and RHCP antenna arrangement.

Connection & Operating Recommendations
Correct connector matching, antenna polarization and cable installation are important when integrating this antenna into a 5.8GHz FPV system. Check the complete RF connection before operation and ensure the antenna is installed in a position suitable for the aircraft’s mechanical layout.
- Confirm RP-SMA Compatibility: Verify that the connected equipment has a matching RP-SMA female interface before installation. Do not force incompatible SMA or RP-SMA connectors together.
- Match RHCP Polarization: Use an appropriately matched RHCP antenna at the opposite end of the FPV link for the intended circular-polarization configuration.
- Route the 120cm Cable Carefully: Avoid sharp bends, pinching, abrasion and tension that could damage the integrated RF cable.
- Choose a Suitable Mounting Position: Position the antenna to reduce obstruction by conductive structures and avoid interference with moving aircraft components.
- Secure the Antenna Assembly: Support the antenna and cable appropriately so that vibration and movement do not place unnecessary stress on the connector.
- Verify Frequency Compatibility: Confirm that the connected transmitter or receiver operates with a compatible 5.8GHz antenna system.
- Inspect the RF Connection: Check that the connector is fully seated and that the cable and antenna assembly are undamaged before use.
