This article covers [Lychae] 2.4GHz 方向性アンテナ Wi.

Overview

The Lychae 2.4GHz High-Gain Circular Polarized Directional Antenna C is a specialized antenna designed for long-range communication with drones and remote control equipment. Its circular polarization design minimizes multipath interference, ensuring stable video transmission and control signal delivery. With a narrow radiation pattern, it excels in pinpoint long-distance links, making it ideal for FPV drone image transmission and industrial RC systems. The connector type C (outer-inner hole) allows compatibility with many 2.4GHz devices.

Key Features

High-gain circular polarization: Radiation angles of E-plane 48° and H-plane 75° concentrate the signal in a specific direction, enabling extended range. The maximum wavelength ratio stays below 1.5 across the 2.4–2.83 GHz band for stable performance. 30W maximum power handling: Supports high-power transmitters for strong signal output. However, due to the narrow beam, precise alignment between transmitting and receiving antennas is critical; misalignment can cause communication loss. Compact and lightweight: Dimensions of 16×12×5 cm and a weight of only 32g make it easy to mount on drones or RC vehicles. The plastic housing is suitable for outdoor use. Connector type C (outer-inner hole): Compatible with common 2.4GHz radios and Wi-Fi adapters. Professional installation is recommended as no mounting guide is included.

Connectivity & Compatibility

This antenna operates in the 2.4GHz band (2.4–2.83 GHz) and uses a C-type connector (outer-inner hole). It can be directly connected to many 2.4GHz transmitters, external antenna ports on Wi-Fi routers, and FPV video transmitters. However, the connector shape may differ from standard RP-SMA or SMA, so verify your device's connector specification before purchase. As a directional antenna, replacing an omnidirectional antenna with this model will significantly change coverage; users should understand the implications.

Product Info

Released on May 12, 2026, on , this antenna is a relatively new product from Lychae, manufactured in China. The package includes only the antenna body; no installation guide is provided, so professional installation is strongly advised. Pricing is competitive with similar 2.4GHz directional antennas on the market. Warranty details are not specified, but 's return policy applies.

Best Use Cases

FPV drone pilots: For long-range video transmission, the high gain and narrow beam help maintain a clear signal over distance. Using a pair of these antennas (one on the transmitter, one on the receiver) yields the best results. RC hobbyists: Ideal for long-range control of airplanes, helicopters, or boats in line-of-sight environments with minimal obstacles. * Industrial wireless applications: In factories or warehouses, the directional pattern reduces interference and improves communication reliability for point-to-point links.
