Skywriter range

I became the proud owner of a skywriter-hat today :)

After research I couldn’t find the exact method of how this board works other than it uses near field.
Is there anyway to increase the range of the near field?
Maybe connecting a larger area for the antenna or something like that?

I’m a software guy and not sure about how the hardware really operates.

Thanks for your suggestions


I pretty sure you can’t alter the range of the Skywriter. If you are interested in how it works, check out Bilge Tank episode 37, where @jon tech talks all the magic behind this board!
