[Ground-station] Ballon launch - lightweight inexpensive 10GHz transmit

[Jordan Trewitt]

How many elements do we want to use? Would 4 be fine? Or would we want more
like 16?

I'll see if I can call Anokiwave later today on my cell, since they have
some pretty small X band phased array chips (and a nice higher power single
TX/RX front end too with a NF of 2.8 dB and 34dBm saturated power output).

Best regards,
