The Amimon Connex kit from CMR has been modified for ease of use with your video cameras by attaching a custom battery pack frame to both the transmitter and receiver, includes modified power cables, and also adding 1/4-20 threaded mounts for mounting to a hotshoe or rig (among other small accessories added to the kit).
Even though this particular Connex kit has been modified, you can always remove the battery mount if you want to use it for your Professional Drone. For those who aren't familiar, Amimon chipsets are licensed to other big brand wireless video transmitters (i.e.Teradek), so they are proven to be reliable and robust. The value in the Connex kit specifically is that it does lack SDI inputs and does not transmit Audio. This system is for HDMI use only (but you can always add an SDI to HDMI converter).
