The ReadyToSky 4 Leaf Clover RHCP RP-SMA Male Antenna is a 5.8GHz circularly polarized antenna designed for FPV video transmitters and receivers, providing improved signal clarity and range by rejecting multipath interference common with standard dipole antennas.

Features

  • 5.8GHz Right-Hand Circular Polarization (RHCP) for superior signal clarity and reduced multipath interference.
  • RP-SMA male connector for direct compatibility with a wide range of FPV VTX and VRX units.
  • Omnidirectional radiation pattern with 3dBi gain for reliable all-around signal coverage.
  • Robust construction with reinforced base at the cloverleaf assembly for increased durability.
  • 50Ω impedance and low VSWR (<1.5) ensure efficient power transfer and stable signal transmission.

Description

This 4-leaf clover antenna utilizes circular polarization to significantly enhance FPV video system performance. The RHCP design is engineered to reject reflected signals that cause multipath interference, a common issue leading to video breakup and ‘ghosting’ with linear antennas. This results in a cleaner, more stable video feed, especially in environments with obstacles and reflective surfaces.

Constructed for the rigors of FPV flight, the antenna features a reinforced neck where the cloverleaf elements meet the connector, reducing the risk of damage from crashes or handling. Its omnidirectional pattern ensures consistent signal strength regardless of the drone’s orientation relative to the receiver, making it an essential upgrade for both racing and long-range FPV applications.

Key Features

  • Circular Polarization (RHCP): Minimizes multipath interference for clearer video and extended effective range compared to linear dipoles.
  • 5.8GHz Frequency Tuned: Optimized for the standard FPV video band, ensuring peak performance for analog and digital HD systems.
  • RP-SMA Male Connector: Standard connector type compatible with most FPV video transmitters and receiver modules.
  • Reinforced Cloverleaf Base: Enhanced structural integrity at the critical stress point to withstand impacts and vibration.
  • Low VSWR Design: Voltage Standing Wave Ratio below 1.5 ensures efficient RF power transfer and protects your VTX.
  • Omnidirectional Radiation: Provides consistent signal coverage in all horizontal directions for reliable video link.

Applications

  • Direct replacement upgrade for stock linear antennas on 5.8GHz FPV video transmitters (VTX).
  • Improving reception on FPV goggles or ground station receivers for analog and digital HD systems like DJI, Walksnail, or HDZero.
  • Long-range and freestyle FPV builds where signal clarity and penetration through light obstacles are critical.
  • Racing drone setups to maintain a stable video link when flying around gates and other pilots.
  • Mounting on diversity receiver setups as one of the omnidirectional antenna options.

Frequently Asked Questions

Is this antenna compatible with my DJI FPV system or Walksnail VTX?

Yes, if your DJI Air Unit, Vista, or Walksnail VTX has an RP-SMA female antenna port, this RP-SMA male antenna is directly compatible. It operates on the standard 5.8GHz frequency used by these digital HD systems and will provide improved signal clarity over a standard linear antenna. Always ensure your VTX power output is within the antenna's handling capability.

What is the advantage of RHCP (Right-Hand Circular Polarization) over a linear antenna?

RHCP antennas are highly effective at rejecting multipath interference, where signals bounce off objects and arrive at the receiver at slightly different times, causing ghosting and video breakup. This results in a cleaner, more stable video feed, especially in environments with trees, buildings, or other pilots. For optimal performance, both transmitting and receiving antennas should use the same polarization (RHCP).

Can I use this antenna on my FPV goggles as a receiver antenna?

Absolutely. This antenna is designed for both transmission (VTX) and reception (VRX). Using it on your goggles or ground station receiver will improve reception quality. It is commonly used as part of a diversity setup, paired with a directional antenna (like a patch) for the best combination of all-around coverage and long-range punch.
