The HORN 58_300R antenna is a directional horn antenna designed for use in unmanned aerial vehicle (UAV) video channels, particularly for FPV (First Person View) flights. Its main feature is high directivity, which allows signal transmission over significant distances with minimal losses. The "58" index in the name indicates the operating frequency range (around 5.8 GHz). "Connector-python" likely refers to the method of attaching the cable to the connector, which provides additional connection reliability and protection against moisture and mechanical damage.
Key features of HORN 58_300R:
| Characteristic | Value |
|---|---|
| Frequency range | 5.2 - 6.2 GHz (center frequency 5.7 GHz). |
| Gain | 20 dBi. |
| Directivity | Narrow beamwidth, approximately 20 degrees horizontal and 15 degrees vertical (at -3 dB level). This means the antenna concentrates the signal in a narrow beam, providing better range and less susceptibility to interference. |
| Polarization | Right-hand circular (RHCP). Circular polarization is less sensitive to antenna orientation, which is important for UAVs that can change their position in space. Left-hand circular (LHCP) polarization options are available (by order). |
| VSWR | < 1.3 in the operating frequency range. |
| Input impedance | 50 Ohm. |
| Maximum power | 50 W. |
| Connector | N type female. This is a reliable and common connector type that provides a high-quality and vibration-resistant connection. |
| Material | Aluminum. |
| Dimensions | Approximately 198 x 168 x 300 mm. |
| Weight | Approximately 1.2 kg. |
| Mounting type | Mast or wall mounting. Usually includes a bracket or other elements for fixation. |
Horn antenna applications:
- UAV video channels (FPV and others). Especially suitable for medium and long-range flights where video signal stability and quality are important.
- Long-range communication systems.
- Telecommunications.
- DIY projects.
Advantages of horn antennas:
- High gain.

Important notes:
- Before purchasing, be sure to clarify the exact technical specifications of the HORN 58_300R antenna with the manufacturer or seller.
- Pay attention to the antenna's polarization and ensure it matches your transmitter's polarization.
- Consider the antenna's size and weight when choosing an installation location.
- "Connector-python" indicates the cable attachment method, which increases connection reliability.
Additional information:
Horn antennas, due to their design, provide high signal directivity, which is critically important for long-range communication, especially in conditions of limited power budget, as is the case with UAVs. A narrow beamwidth allows concentrating transmitter energy in a specific direction, minimizing signal loss and interference from other sources.
Choosing the right antenna is a key factor in ensuring a stable and high-quality UAV video channel. When choosing the HORN 58_300R antenna, consider the following factors:
- Operating frequency: Ensure that the antenna's frequency range matches your video transmitter's frequency.
- Communication distance: The antenna's gain affects the communication range.
- Terrain conditions: In urban areas or complex terrain, antennas with different characteristics may be required.
