Optimizing each facet of your FPV drone setup is vital to attaining the very best video high quality and vary. Understanding the SWR of your 5.8GHz antenna will help resolve which frequency or channel it is best to use for optimum efficiency. Not everybody has the instruments to measure SWR, so I’ve performed in depth checks on the antennas I personal to share their SWR plots with you.
Creating content material like this requires time and assets, and I’ve invested a number of hundred {dollars} in buying a few of these antennas for testing. I hope you discover this data worthwhile, and in that case, please think about supporting me on Patreon: https://www.patreon.com/oscarliang
SWR Plots Defined
What’s antenna SWR: https://oscarliang.com/best-fpv-antenna/#SWR. Inquisitive about 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 throughout 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 ceaselessly use.
- Channel Optimization: Use the SWR charts to determine which channels supply the very best efficiency to your chosen antenna.
- Matching Receiver Antennas: Be certain that antennas for the receiver have an identical resonance frequency for the very best outcomes.

Conclusion
SWR performs a pivotal function in attaining dependable FPV video hyperlinks. By understanding antenna SWR, pilots could make educated selections, deciding on essentially the most appropriate antennas and frequency/channel for his or her flights. I plan to proceed testing extra antennas and can repeatedly replace this put up. When you’ve got any specific antenna you need me to check, let me know within the remark. Pleased flying!
