Optimizing each facet of your FPV drone setup is vital to reaching the very best video high quality and vary. Understanding the SWR of your 5.8GHz antenna might help resolve which frequency or channel you must use for optimum efficiency. Not everybody has the instruments to measure SWR, so I’ve carried out in depth checks on the antennas I personal to share their SWR plots with you.
Creating content material like this requires time and sources, and I’ve invested a number of hundred {dollars} in buying a few of these antennas for testing. I hope you discover this data precious, and in that case, please contemplate supporting me on Patreon: https://www.patreon.com/oscarliang
SWR Plots Defined
What’s antenna SWR: https://oscarliang.com/best-fpv-antenna/#SWR. Interested in measuring antenna SWR? Take a look at my tutorial for a deep dive into the method:: https://oscarliang.com/litevna-measure-antenna-swr/.
The antennas on this publish 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
- Choosing the Proper Antenna: Contemplate antennas with constantly low SWR throughout the channels you incessantly use.
- Channel Optimization: Use the SWR charts to establish which channels provide the very best efficiency in 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 reaching 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 commonly replace this publish. When you’ve got any specific antenna you need me to check, let me know within the remark. Completely happy flying!
