Description

The Foxeer Lollipop 4 Plus SMA antenna is engineered for FPV pilots seeking a reliable omni-directional signal solution. Its design prioritizes a consistent radiation pattern with an axial ratio close to 1, which is critical for maintaining signal integrity and polarization matching in dynamic flight environments. The use of printed circuit and gold-plating technology ensures uniform electrical performance and long-term corrosion resistance.

This antenna’s compact form factor (Φ11x60mm) and robust PC+ABS housing make it suitable for both airborne and ground station applications, where durability and weight are key considerations. The optimized impedance matching results in a low Voltage Standing Wave Ratio (VSWR), translating to efficient RF energy transfer and extended operational range for racing, freestyle, and cinematic FPV drones.

Key Features

  • Optimized RF Circuitry: Printed circuit board design with gold-plated contacts ensures consistent impedance and minimal signal loss across the 5.8GHz band.
  • Circular Polarization: Right-Hand Circular Polarization (RHCP) effectively mitigates signal fading caused by reflections and orientation changes during aggressive maneuvers.
  • Broad Operational Bandwidth: Covers the full 5.5-6GHz spectrum, ensuring compatibility with all standard 5.8GHz FPV channels and video transmitters.
  • High-Efficiency Design: 98% radiation efficiency maximizes transmitted power, directly contributing to improved video link range and clarity.
  • Ruggedized Housing: The PC+ABS composite case provides excellent impact resistance and protects the internal antenna element from physical damage and environmental factors.
  • Lightweight Airframe Integration: At just 7.8 grams, it adds negligible weight to FPV builds, preserving flight performance and battery life.

Applications

  • Primary or diversity antenna for 5.8GHz FPV goggles and ground station receivers.
  • VTX antenna for micro and mini FPV racing drones where a lightweight omni-directional pattern is required.
  • Replacement antenna for digital HD FPV systems (e.g., DJI FPV, Walksnail, HDZero) operating in the 5.8GHz band.
  • Signal enhancement for long-range cinematic or freestyle quadcopters when used in conjunction with directional antennas.
  • Backup or spare antenna for FPV pilots to ensure uninterrupted flying during events or repairs.

Frequently Asked Questions

Is the Foxeer Lollipop 4 Plus antenna compatible with my DJI FPV Goggles V2?

Yes, the Foxeer Lollipop 4 Plus uses a standard SMA connector and operates on the 5.8GHz band, making it directly compatible with DJI FPV Goggles V2 and other goggles that use SMA-type antenna ports. Its RHCP polarization matches the typical output of most 5.8GHz video transmitters, ensuring optimal signal reception.

What is the advantage of an axial ratio close to 1?

An axial ratio close to 1 indicates nearly perfect circular polarization. This is critical for FPV as it ensures consistent signal strength regardless of the antenna's orientation relative to the transmitter. It minimizes signal fading during rolls and flips, providing a more stable video feed with less multipath interference.

Can I use this antenna on my video transmitter (VTX) as well as my goggles?

Absolutely. The Foxeer Lollipop 4 Plus is designed for dual use. Its omni-directional radiation pattern is ideal for both transmitting from the drone and receiving on the goggles. Using matched RHCP antennas on both ends maximizes link efficiency and range. Ensure your VTX also has an SMA connector.
