Description

The Generic 5.8G Lollipop Antenna is engineered for reliable FPV video transmission, utilizing a circularly polarized design to mitigate signal degradation caused by reflections and orientation changes. Its omnidirectional pattern ensures consistent video link quality during aggressive freestyle or racing maneuvers where the drone’s orientation is constantly shifting.

Built with a 50-ohm impedance-matched coaxial cable and connector, it integrates seamlessly into 5.8GHz analog video systems. The antenna’s structural design prioritizes a favorable axial ratio and smooth radiation pattern, contributing to a stable and clear video feed with reduced video snow and breakup at range.

Key Features

  • RHCP (Right-Hand Circular Polarization) minimizes signal nulls and multipath distortion for cleaner video.
  • Omnidirectional radiation pattern provides consistent signal strength in all horizontal directions.
  • RP-SMA male connector ensures broad compatibility with FPV VTXs, VRX modules, and goggles.
  • Durable coaxial cable and housing withstand the vibrations and impacts typical in FPV flight.
  • Optimized for the 5.8GHz ISM band, covering channels used by analog VTX systems.
  • Lightweight design (11g) minimizes added mass on micro and mini quadcopter builds.

Applications

  • FPV racing and freestyle drones requiring a compact, omnidirectional VTX antenna.
  • Micro and Whoop-class quadcopters where low weight and small size are critical.
  • Ground station or FPV goggles as a replacement or diversity receiver antenna.
  • Long-range analog FPV builds utilizing a 5.8GHz video system.
  • DIY drone projects needing a standardized RP-SMA connector antenna.

Frequently Asked Questions

Is this antenna compatible with my DJI FPV Goggles or Walksnail VRX?

No, this antenna is designed for analog 5.8GHz video systems. DJI and Walksnail digital HD FPV systems use different frequency bands and proprietary connectors (typically MMCX or U.FL). You must use antennas specified for your digital video system.

What is the advantage of using an RHCP antenna over a linear polarized one?

RHCP antennas are circularly polarized, which makes the video signal more resistant to multipath interference caused by signal reflections off the ground or objects. This results in less video 'sparkles' and breakup, especially in environments with many obstacles. Both the transmitter and receiver must use the same polarization (RHCP) for optimal performance.

Can I use this antenna on my video transmitter and my receiver/goggles at the same time?

Yes, for the best possible video link, it is recommended to use matching RHCP antennas on both the drone's video transmitter (VTX) and the ground station or goggles' video receiver (VRX). This practice, known as using a 'matched set,' maximizes signal strength and minimizes polarization loss.
