In modern combat, where mission success depends directly on the quality of the control signal, the choice of antenna equipment becomes critical. Directional passive Yagi antenna (Yagi-Uda), optimized for the 800-915 MHz band, is designed for professional pilots who require maximum flight range and a stable link even in intense enemy electronic countermeasures.

Thanks to the high gain of 14 dBi, this antenna significantly extends the range of standard transmitters (ELRS, Crossfire), providing confident control of the drone at distances inaccessible to conventional antennas.

Why is the Yagi antenna indispensable for tactical tasks?

Unlike omnidirectional antennas ("whips"), the Yagi antenna focuses all the signal energy into a narrow beam. This not only increases the range, but also effectively cuts out side interference, which is vital in the noisy radio air of the front zone.

• Concentrated signal: 14 dBi gain allows you to “break through” Electronic warfare interference and maintain control over long distances.
• Operation in priority bands: Optimization for frequencies of 800-915 MHz is ideal for the most popular long-distance communication protocols.
• High efficiency (Low SWR): An indicator of 1.4 guarantees efficient use of transmitter power without the risk of overheating the output stages of the console.
• Reliability and lightness: The simple and robust design is resistant to wind loads and is completely ready for operation in field conditions.

Technical and tactical characteristics (TTX)

This model is a completely passive device, which simplifies deployment (does not require power) and makes it extremely reliable in the field.

Expert assessment: Advantages in the EW zone

The 800-915 MHz range is considered the "gold standard" for FPV systems due to its excellent penetration ability and the ability to bypass obstacles (terrain, vegetation). Using a directional antenna with a narrow radiation pattern allows the pilot to literally "hide" behind a narrow communication beam, making his position less vulnerable to direction finding by enemy electronic reconnaissance (ELINT).

Important note: To achieve maximum results, the antenna must be clearly oriented towards UAV. Even a small deviation from the axis can lead to a decrease in the signal level, so it is recommended to use the antenna on external masts or tripods.

Compatibility and installation

The antenna is equipped with a standard SMA connector, which makes it a universal solution for modern equipment:

1. TBS Crossfire: Full support for 868/915 MHz frequencies.
2. ExpressLRS (ELRS): An ideal choice for 900 MHz modules.
3. Remote repeaters: Can be used as the main transceiver antenna at ground stations.
