Reach + required components

Total noob here, apologies in advance…

I have a balloon camera rig that I use for coastal mapping. Reach sounds like an obvious addition to my setup. However, it’s not clear to me what additional components I would need.

Could someone please lay out in basic laymen’s terms the complete list of equipment necessary to use Reach on a small aerial platform?

You would need two Reach modules plus some communication equipment (433\900 radio, 3G modem etc) and that’s it.
