Signal Extenders for your DJI Drone… yes or no?

So, this is a question we get asked and see asked in forums on a regular basis!  Do those little signal extenders that sit on your remote control actually work at extending the signal for your DJI drone.

We can only talk from our experience obviously – but, yes the signal extenders do work!  Our thoughts though are below! 🙂

On the DJI Spark and DJI Mavic Air –

When we fly our DJI Spark and DJI Mavic Air, we have found (and had feedback from customers) that the signal between your drone and remote can start to get a bit fuzzy anywhere in between 200m and 500m.   This signal drop out results in patchy video coming back to the device, and will also sometimes see the drone drop out of signal.

On both the DJI Spark and DJI Mavic Air we have found based upon our own testing that the signal extenders have hugely improved performance here!

On the flip side…

When we fly our DJI Mavic Pro and the DJI Mavic 2 Pro (so would be the same for the Mavic 2 Zoom), given both run versions of Occusync by DJI the signal runs pretty well – without needing to extend the signal.   Whilst the signal extenders may provide additional benefit – for most peoples flying, it would really not be necessary in our view!

(We also sell TWO versions of these – there is a version with just the signal extenders, but also a version with signal extenders and a sunhood that will suit most mobile phones as well 🙂 ) 

Just a note on using the signal extenders as well though – always make sure the remote (and subsequently the signal extenders) is facing the direction of your drone.   Don’t fly your drone behind you, as the signal extenders are capturing the signal from the forward facing direction.   Hopefully that makes sense! 

I’m not into all the ‘technical’ how things work when it comes to signals, so just write from our own experience here – and feedback we have had from customers along the way.   Everyone’s experience will vary – depending upon the conditions and environment they are flying etc.

Please note!

Also – please always bear in mind the rules from the relevant authorities, whether it be CASA and local governments in Australia, or the comparative organisations in other countries for rules around visual line of sight, or maximum flight distances that may be allowed!
