Range Boosters do they work?

[WValentine0611]

I’m curious about the range boosters, the kind that slides over the antennas. Do they work and would they work on the SC?

My Zoom came with one I barely use, I saw a video on utube a guy used aluminum foil to boost his antenna. I never flew mine far away to see the full range, I also noticed my Ipad mini 4 start freezing up, loosing signal when I pass a mile range, at this point I am not sure if the drone or the tablet is the issue. I tried my antenna booster before and didn't noticed any difference.

You should try the 4 Hawks: RaptorSR for DJI Mavic and Spark drone

I use this for my Inspire2 , the range is signifantly better. Unfortunately the threads don`t fit so you have to open the controller due to transfer the cables:

The easier way is to change transmission from CE to FCC since you live outside the US

Without getting into the nitty-gritty of RF design, if done properly they will shape and reflect the signal emitted by the antennae so that more of the emitted radio waves are transmitted towards the drone. Similarly, they should bounce more of the received signal back onto the antenna, boosting the apparent amplitude they sees.

The should, however, be constructed taking into account the properties of the specific frequencies and amplitudes being used to gain the maximum benefit. Failing to do this, as is likely with a DIY tin-foil approach, could quite likely actually end up reducing the range of the signal. Frankly, given even the stock antennae is pretty good to around 5km (probably further, but that's the max I've gone so far), unless you're in the habit of doing very long range flights or are getting alarms about strong RF interference on a regular basis they're probably not worth the bother.
