- How Far Can ELRS Go (signal strength comparison)? - 2.4gHz vs 900mHz Antenna Test
TLDR: My test is pointless, with line of sight, Rx antenna makes the biggest difference. Need to redo the test without line of sight.
I recently switched a couple of my quads over to 2.4gHz and wasn’t getting the same range as with 900mHz so I though I would fly them back to back and see how they compare. I limited myself to 500m flights and all sub 250g drones and compared signal strength rather than out right distance.
The receiving antenna had the biggest impact on range/signal strength. I was flying line of sight so my challenges with range are likely a penetration issue. I will have to redo the test with some trees in the way of the signal.

Thank you for taking the time to do this
Debating on getting a drone with either 2.4ghz elrs or 915mhz what is the difference in responsiveness? Is it very noticeable for your stick imputs?
I don't notice, but I'm not a racer, I'm a pretty casual/slow flyer. I'm flying digital so there would be some latency from that as well, but I don't notice that either. There is more selection for the 2.4ghz as it is more common. The 900mhz is still easy to get, lots of options on aliexpress, just not as much as 2.4ghz.
What Rx are you using for 900?

What happened with the second flight? Didn't look like a failsafe still in high 90s LQ and only -88dbm?
It was fine, just turned around because I hit 500m distance.
@@reileymckerracher9181 I see
So based on your results 2.4 vs 900 didnt have much difference in range?
I didn't really notice any, but it was clear line of sight for the flights. I would like to try again in an area with obstacles in the way of the signal as I still think 900mhz gives a more robust link. Maybe I would notice a difference with more distance too.
@@reileymckerracher9181 I'm more interested in obstacles than distance. As in flying through dense trees close to the ground.
@@im_gldn me too! might have to try it again with that in mind!
I’m just getting my feet wet with ELRS and was wondering if, what’s the difference between the RP1 ELRS 2.4 and the RP3 ELRS 2.4. Does one have more range?
@@dronepilot260rc i dont think theres much of a different in performance, except for the diversity models. wouldnt call my self noob but im no "know it all"
