Yagi Antenna 400MHz 4 Sections 8.6 dBi by

The Yagi antenna is designed for directional signal amplification in the 400 MHz band. This model from the manufacturer combines high efficiency and ease of installation, making it suitable for radio communication, amateur radio, narrowband data transmission systems, and other applications where antenna stability and directionality are important. The product belongs to the category: Antennas > Yagi Antennas, optimized for use in both stationary and mobile installations.

The antenna body is made of aluminum, ensuring lightness and corrosion resistance for outdoor operation. The compact dimensions of the design — 680×366×60 mm — and low weight — 294 g — facilitate mounting on masts, roofs, and mobile platforms. A standard SMA connector is used for connection, ensuring compatibility with most modern receivers and transmitters.

Key Advantages

• High gain: 8.6 dBi for improved signal reception and transmission quality.
• Operating frequency: 400 MHz — suitable for narrowband solutions.
• Number of sections: 4 (directors), providing pronounced antenna directionality.
• Beam angle: 40° — provides clear direction and minimizes side lobes.
• Polarization: linear — compatible with typical receivers.
• Material: aluminum — lightweight and weather-resistant.
• Connector: SMA — standard connector solution for equipment connection.
• Dimensions and weight: 680×366×60 mm; weight — 294 g.

The Yagi Antenna 400MHz 4 Sections 8.6 dBi is optimal for use in weak coverage conditions when it is necessary to amplify the signal in a specific direction and reduce interference from other sides. Thanks to its directional characteristic and moderate beam angle, it allows for the creation of a more stable communication channel, which is especially important for professional applications and amateur networks.

Installation of the structure does not require complex tools: the lightweight aluminum frame and well-thought-out mounting design allow for quick installation of the antenna on standard masts or brackets. It is recommended to additionally seal connection points during outdoor installation to prevent moisture from entering the SMA connector contact areas.

Application Recommendations

• Orient the antenna towards the signal source to achieve maximum gain, using the direction of the directors for precise aiming.
• Check the compatibility of the SMA connector with your equipment; use adapters if necessary.
• For long-term operation, ensure protection of mounting points from corrosion and moisture.
• Consider the 40° beam angle when planning the location to minimize the impact of extraneous interference sources.

This model demonstrates technical precision, ease of installation, and reliable performance characteristics, making it a good choice for engineers, operators, and enthusiasts looking for an effective directional antenna in the 400 MHz band.
