Tổng quat

Các 150mm Triple Feed Patch 5.8GHz 14dBi Pagoda Array FPV Antenna is a high-performance circularly polarized antenna designed for long-range FPV, Từ xa UAV, and high-stability video links. Unlike traditional FR4-based patches that suffer heavy loss at 5.8 GHz, this antenna uses a coupled-patch array structure that significantly improves radiation efficiency, axial ratio, and overall link reliability. Its wide bandwidth, ultra-low VSWR, and optimized low-sidelobe pattern ensure stable video transmission even during aggressive maneuvers or off-axis flight angles.

Tính năng, đặc điểm

1. High Radiation Efficiency

• Avoids typical FR4 losses by using a coupled-patch array design.

• Simplified feed network reduces internal loss and improves consistency.

2. Excellent Circular Polarization (Axial Ratio Performance)

• Outstanding axial ratio not only on-axis but also off-center.

• Ensures clean CP signal reception and superior multipath resistance.

3. High Gain With Optimized Pattern Control

• 14.4 dBi gain provides strong long-distance performance.

• Slightly reduced theoretical gain to maintain low sidelobes and clean CP pattern.

4. Ultra-Low Sidelobes

• Energy is concentrated in the main lobe for higher signal stability.

• Wider but more usable main beam, ideal for dynamic FPV applications.

5. Wide Operating Bandwidth

• Covers 5.47 GHz đến 6.13 GHz for compatibility with most 5.8 GHz FPV systems.

6. Durable and Lightweight

• nhựa + metal structure ensures long service life while maintaining low weight.

• Được thiết kế cho máy bay không người lái, fixed-wing FPV, và trạm mặt đất.

✔ FAQ

Q1: Is this antenna compatible with all 5.8 GHz FPV systems?
Vâng. It supports 5.47–6.13 GHz, covering all major FPV VTX/VRX frequency bands.

Q2: What is the real-world range improvement?
Với 14.4 dBi gain and high axial ratio, it provides significantly more stable long-distance video, especially in noisy RF environments.

Q3: Can this be used on both TX and RX?
It is mainly recommended for the người nhận side due to its directional high-gain design, but can be used on TX when properly aligned.

Q4: Does the low-sidelobe design really help FPV?
Vâng. It reduces unwanted multipath reflections and improves signal stability during turns, banking, or off-axis flight.

Q5: Is it weather resistant?
It is built with plastic + metal materials suitable for outdoor use, but heavy rain may affect RF performance.

Q6: Why is the axial ratio important?
A low axial ratio provides better circular polarization, meaning clearer video with less interference, especially through obstacles or during high-angle flight.
