High Data Rate RF Link?

What possibilities are there for a high data rate full duplex RF data link (video + telemetry + RC) for UAVs other than Satcom?

We can have a directional tracking antenna at the ground station but what about onboard antenna? I am not in favor of onboard omi-directional antenna to transmit high power signal in all directions wasting the power!

  • If the ground station antenna is directional, it is more sensitive in terms of what it can receive, which compensates for the efficiency of the unidirectional drone antenna. In my project (https://kitware.github.io/adapt/), we have established long-range (> 1 km as long as line of sight) using a direction ground station antenna and unidirectional drone antenna.
