Hi everybody,

I'm making and antenna tracker for my pixhawk + DJI Lightbridge octocopter. As we know, DJI provides absolutely no technical documentation on any of their products, so I wonder if anyone here has any information on the workings of the lightbridge. My question is this:

Does the slave receiver (i.e. gimbal controller) receive its video directly from the air module, or is it received by the master, then relayed to the slave.

This questions is so I know whether to mount the second receiver on the tracker too, and attach a directional antenna, or to keep the omni antennae and mount it to the gimbal controller's Tx.

While I'm here, I'll ask this, too:
If I place the two lightbridge ground modules right next to each other, will they interfere with each other? Even though the slave should theoretically only be in passive mode?

Thanks in advance,
Patrick
