SWR Plots of FPV Antennas – Know Your Greatest Frequency/Channel

SWR Plots of FPV Antennas – Know Your Greatest Frequency/Channel


Optimizing each side of your FPV drone setup is essential to attaining the perfect video high quality and vary. Understanding the SWR of your 5.8GHz antenna may help determine which frequency or channel it’s best to use for optimum efficiency. Not everybody has the instruments to measure SWR, so I’ve performed in depth exams on the antennas I personal to share their SWR plots with you.

SWR Plots Defined

What’s antenna SWR: https://oscarliang.com/best-fpv-antenna/#SWR. Interested in measuring antenna SWR? Try my tutorial for a deep dive into the method:: https://oscarliang.com/litevna-measure-antenna-swr/.

The antennas on this put up are listed alphabetically. The plot markers are as follows: Marker 2 is at 5.6GHz, Marker 3 is at 5.8GHz (the middle of the graph), and Marker 4 is at 6.0GHz. Marker 1 highlights the place the bottom SWR is discovered inside the sweep vary of 5.4GHz to six.2GHz.

Suggestions for Enhancing Your FPV Video Hyperlink

  • Deciding on the Proper Antenna: Take into account antennas with constantly low SWR throughout the channels you incessantly use.
  • Channel Optimization: Use the SWR charts to establish which channels provide the perfect efficiency in your chosen antenna.
  • Matching Receiver Antennas: Make sure that antennas for the receiver have an identical resonance frequency for the perfect outcomes.

Conclusion

SWR performs a pivotal position in attaining dependable FPV video hyperlinks. By understanding antenna SWR, pilots could make educated choices, choosing essentially the most appropriate antennas and frequency/channel for his or her flights. I plan to proceed testing extra antennas and can recurrently replace this put up. If in case you have any specific antenna you need me to check, let me know within the remark. Pleased flying!
