Advantages

• Wide Frequency Range: Operation in the 4700–6000 MHz range makes the antenna versatile for modern FPV solutions.
• High Gain 12 dBi: Ensures strong signal reception and transmission, improving video quality during flights.
• Focused Coverage (30°): Minimizes interference from side sources and increases communication range.
• Low Voltage Standing Wave Ratio (VSWR = 1.5): Guarantees efficient transmission with minimal energy loss.
• Design and Materials: 1 mm enameled copper wire and a 54 mm diameter reflector ensure stable electrical parameters and reliability.
• Power up to 50 W: Suitable for long flights and active use in field conditions.

Where and How to Use

The antenna is ideal for FPV video systems — pursuit, control, and live video streaming from drones and quadcopters. It guarantees uninterrupted video signal transmission during flights, especially in intense radio frequency environments, thanks to its LHCP (Left-Hand Circular Polarization), which reduces interference with other antennas.

Features and Additional Information

The model has an open design and 12 turns, allowing for high directivity and beam focusing. The coaxial cable length of approximately 9 cm and standard SMA connector ensure easy integration with many FPV transmitters and receivers. A weight of about 52 g makes the antenna a lightweight option for most unmanned platforms.

Important: Custom antenna assembly is possible to meet specific customer requirements, allowing parameters to be adjusted for your tasks (e.g., different number of turns, cable length modification, adjustment to other frequency limits within the design's capabilities).

This antenna from SkyReach is an excellent choice for both professionals and FPV flight enthusiasts who require reliable, directional, and powerful video signal reception/transmission at frequencies of 4700–6000 MHz.
