Description

The 5.8G Lollipop Antenna is engineered for FPV drone applications, providing a robust circularly polarized signal that helps mitigate multipath interference common in dynamic flight environments. Its design prioritizes a smooth omnidirectional radiation pattern and a good axial ratio, contributing to stable video link performance.

Constructed with a simplified manufacturing process, this antenna delivers a high-value performance-to-weight ratio, making it a suitable choice for racers and freestyle pilots seeking to minimize weight without sacrificing video feed reliability. The antenna is rated for operation in extreme temperatures from -40°C to 85°C.

Key Features

  • RHCP Omnidirectional Design: Right-Hand Circular Polarization provides resistance to signal fading and improved performance in cluttered RF environments compared to linear antennas.
  • Optimized Radiation Pattern: Engineered for a smoother, more consistent radiation field and a superior axial ratio for enhanced signal integrity.
  • Compact & Lightweight Build: Minimal footprint and weight (8g) reduce drag and balance issues on micro and lightweight drone builds.
  • Broad Operating Temperature: Rated from -40°C to 85°C for reliable performance in diverse climatic conditions.
  • Direct SMA Connectivity: Features a standard SMA Male plug for direct attachment to compatible 5.8 GHz video transmitters and receiver modules.

Applications

  • FPV racing and freestyle drones requiring a lightweight, omnidirectional VTX antenna.
  • Micro and Whoop-class builds where minimal antenna size and weight are critical.
  • As a replacement or upgrade antenna for 5.8 GHz analog video transmitters and receivers.
  • DIY drone projects needing a compact, circularly polarized antenna for improved video signal clarity.

Frequently Asked Questions

Is this antenna compatible with my 5.8 GHz analog FPV goggles?

Yes, this antenna is directly compatible with any 5.8 GHz FPV video receiver or transmitter that uses a standard SMA female connector, which is common on most analog goggles and VTX modules. Ensure your device uses RHCP polarization for optimal performance.

What is the advantage of RHCP polarization over a linear antenna?

RHCP (Right-Hand Circular Polarization) helps maintain a stable video link when the drone is banking, rolling, or flying in environments with signal reflections. It reduces video signal dropouts and multipath interference compared to linear polarized antennas, providing a more reliable feed.

Can this antenna be used on a digital HD FPV system like DJI or Walksnail?

No, this antenna is designed for the 5.8 GHz analog FPV band. Digital HD systems like DJI FPV, Walksnail, or HDZero use proprietary protocols and specific antenna designs. Using this antenna on a digital system will likely result in no signal or severely degraded performance.
