Long-range FPV flying has gained popularity among drone fanatiks. A successful long-range flight depends on the quality of your antenna. In this post, we’ll dive into three different types of antennas that are well-suited for long-range in the 5.8 GHz :
Pagoda, Pagoda Super Long, and the Helical antenna.
Understanding the strengths and limitations of each will help you make an informed choice for your flying style and needs.
Pagoda Antenna (5.8 GHz Edition)
The Pagoda antenna, a circularly polarized omnidirectional design by Maarten Baert, is a reliable choice for standard FPV systems. This version is optimized for the 5.8 GHz frequency range, making it an excellent all-around antenna for most FPV applications.
Key features:
- Frequency range: 5.7-5.9 GHz
- Gain: 2.5 dBi
- VSWR: Less than 1.3
- Polarization: RHCP or LHCP available
- Cable length: 140mm
The Pagoda 2.1 version has been enhanced with modified holes that ensure a better fit for the cable, providing improved durability. Its omnidirectional radiation pattern ensures consistent signal coverage in all directions, making it a versatile choice for various flying styles, whether you’re weaving through tight spaces or exploring open areas.
Pagoda Super Long
For those seeking extended reach, the Pagoda Super Long antenna is an excellent option. With lenght of 210mm (from end to end of antenna), this antenna is designed for long-range FPV flying in the 5.8 GHz band.
Key benefits:
- Enhanced signal propagation
- Potential for greater range
- Improved performance in challenging environments
The extra length of the Pagoda Super Long can be particularly advantageous when flying in areas with obstacles or varied terrain. It helps maintain a stronger signal over longer distances, which is crucial for successful long-range flights.
5 Turn Helical Antenna
Helical antenna is directional antenna well known for its high gain and wide frequency range, making it a good choice for long flights applications for 5.8 GHz band. If you are looking to push your FPV range to its limits, the Helical antenna may be the perfect solution.
Key features:
- Frequency range: 5.7-5.9 GHz
- Gain: 11 dBi
- Beam width: 45 degrees at peak gain, up to 100 degrees at shorter distances
- Polarization: RHCP or LHCP available
- VSWR: Less than 1.2
The Helical antenna’s focused beam allows for maximum range in a specific direction, making it ideal for long-distance flights where you need a strong, reliable connection in one direction.
Antenna Placement and Height
Proper antenna placement and height are crucial for optimal performance in long-range FPV flying, regardless of the antenna you choose. Here’s why:
1. Elevated position: Placing your antenna higher reduces interference from nearby objects and ground reflections.
2. Improved line of sight: A higher antenna position increases the likelihood of maintaining a clear signal path to your drone.
3. Extended range: Better line of sight and less interference contribute to a greater effective range.
4. Better signal quality: Elevation often leads to cleaner signals with less multipath interference.
5. Decreased ground effect: Raising the antena a minimizes signal distortion caused by reflections off the earth’s surface.
Choosing the Right Antenna for Your Needs
When selecting an antenna for long range FPV in the 5.8 GHz band, consider these factors:
1. Flying style: Omnidirectional antennas like the Pagoda are great for diverse flight patterns, while directional antennas like the Helical excel in focused, long-distance flights.
2. Frequency requirements: Make sure the antenna is tuned to the specific frequencies your system uses within the 5.8 GHz band.
3. Polarization: Ensure the polarization (RHCP or LHCP) matches your other equipment for optimal performance.
4. Size and weight constraints: Consider the antenna’s dimensions and weight, particularly if it will be mounted on goggles or in a space-limited setup.
5. Range requirements: Higher gain antennas generally offer better range but might have a narrower beam width; consider this based on your flying environment.
Conclusion
Selecting the right 5.8 GHz antenna is essential for successful long-range FPV flying. Whether you choose the versatile Pagoda, the extended reach of the Pagoda Super Long, or the high-gain Helical antenna, understanding your specific needs and properly positioning your antenna will help you achieve the best possible performance. Always fly responsibly and stay within legal limits to ensure a safe and enjoyable FPV experience.
