Best FPV frequency: 1.3 GHz vs 3.3 GHz vs 5.8 GHz, physics vs reality


This is a companion topic for our recent blog post on blog.unmanned.tech

Let’s have a gander at the latest blog post where we dissect the thrilling world of FPV frequencies: 1.3 GHz, 3.3 GHz, and 5.8 GHz. The theory suggests that lower frequencies should grant us better range and obstacle handling, which certainly sounds delightful. However, reality has a cheeky habit of proving otherwise.

In our grand experiment, 3.3 GHz was supposed to outshine 5.8 GHz with a 1.75 times range advantage, but it turned out to be about as impressive as a soggy biscuit. 1.3 GHz, the darling of the long-range crowd, didn’t fare much better, largely due to GPS interference and some rather uncooperative hardware. Who knew physics had such a dry sense of humour?

So, what’s the takeaway? If you want reliability and simplicity, stick with 5.8 GHz—it’s like the old reliable friend who always shows up with a cup of tea when you need it. Fancy a bit of tinkering? Then 3.3 GHz and 1.3 GHz could be the new toys for you, but do remember to read the small print on legality and be prepared for a bit of channel planning.

Great read! Nothing beats real-world testing over pure theory.

The “soggy biscuit” description for 3.3GHz made me chuckle, but it’s so true. 1.3GHz is definitely a nightmare with GPS desense unless you’re running heavy filtering and massive setups.

5.8GHz really is the reliable workhorse of FPV. Thanks for sharing the test results, heading over to check out the video now!
