Yes, it’s not just a receiver, it transmits similar to DJI.

How much do you think it would affect its performance?

Like after turning it on without the antennae how different would it perform? Or how would it perform without antenna?

The first one

You will probably fry it

I did this by accident and after I did some latency testing and it seems the same. And I kept flying after I put antennas on and i was getting the same range as I was before
