Description

The Triple Feed Patch 5.8GHz Antenna is engineered for FPV pilots seeking reliable, high-gain directional reception. Its triple-feed design creates a robust circularly polarized radiation pattern, minimizing signal nulls and multipath distortion common in urban or reflective environments. The antenna’s construction prioritizes materials with low dielectric loss at 5.8GHz, resulting in a radiation efficiency significantly higher than typical FR4 PCB patches.

With a half-power beamwidth of 55 degrees in both horizontal and vertical planes, it provides a focused yet usable lobe for targeting video transmitters. The integrated SMA male pigtail offers a direct, low-loss connection to compatible receivers or ground station equipment, making it an ideal upgrade for long-range FPV exploration, racing gate penetration, and HD digital video links where signal clarity is paramount.

Key Features

High-Gain Directional Pattern: Delivers 9.4 dBi of focused gain to extend video range and punch through interference.
Superior Circular Polarization: Maintains an axial ratio below 1.3, ensuring effective rejection of reflected signals and reduced multipath glitches.
Optimized Bandwidth: Covers 660 MHz across the 5.8GHz ISM band (5.47–6.13 GHz), compatible with all common analog and digital FPV channels.
Low-Loss Construction: Utilizes materials with high radiation efficiency (83.5%) to maximize transmitted power and minimize thermal losses.
Integrated Coaxial Pigtail: Comes with a semi-rigid SMA male to SMA male cable for a secure, direct connection without additional adapters.
Stable Beamwidth: 55-degree half-power beamwidth provides a balance between directionality and practical aiming tolerance.

Applications

Long-range analog or digital HD FPV ground station receiving antenna.
Directional antenna for FPV racing to penetrate interference from multiple pilots.
Fixed installation on tracking ground stations for extended exploration and mapping drones.
Replacement for low-gain omnidirectional antennas on video receivers for improved signal-to-noise ratio.

Frequently Asked Questions

Is this antenna LHCP or RHCP?

The Triple Feed Patch antenna is a directional circularly polarized antenna. Its specific handedness (LHCP or RHCP) is determined by its internal feed network construction and is typically fixed. You must ensure it matches the polarization (LHCP or RHCP) of your transmitting antenna on the drone for optimal signal reception and cross-polarization rejection.

What is the advantage of the triple-feed design?

The triple-feed design improves the axial ratio, which is a measure of how purely circular the polarization is. A better axial ratio (closer to 1) means the antenna maintains effective circular polarization over a wider angle off its central bore-sight, leading to more consistent signal strength and better rejection of multipath reflections when the antenna isn't perfectly aimed.

Can I use this antenna with both analog and digital HD FPV systems?

Yes. With a center frequency of 5.8GHz and a broad 660 MHz bandwidth covering 5.47–6.13 GHz, this antenna is compatible with the entire 5.8GHz ISM band. It will work with standard analog VTXs, DJI FPV Air Units, Walksnail, and HDZero systems operating within that frequency range, provided the connector type (SMA) is compatible.

Does it come with a mounting bracket?

The package includes the antenna element and an SMA male to SMA male coaxial pigtail. It does not include a dedicated mounting bracket. The flat, compact patch design is typically secured using adhesive-backed Velcro, double-sided tape, or can be integrated into a custom 3D-printed enclosure for a ground station.
