Shouldn I be concerned with the MHX transceivers cable sticking out of the side of the CubeSat Kit?
Not really. The MHX transceiver is quite large compared to the CubeSat, and we felt that this was the best installation location for it. The cable is still within the CubeSat specifications regarding items protruding above the CubeSat sides. We recommend you use some mechanical means to ensure that the cable will stay connected to the transceiver. The fact that it is exposed to space is not cause for worry.
