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.

You can jump to 3:05 to see the results.
