So I've been having my vtx signal on my air unit hit 2 bars before my TX even drops to 3. Is this normal? Do other people see the TX and vtx signal drop off at the same time, or is the vtx signal inherently weaker? Has anyone got it the other way around by any chance?

Trying to troubleshoot my first ever quad so I don't have another air unit for reference.

Like you, my vtx signal is usually a bar lower than my transmitter signal. I figure that's normal.  But  occasionally the inverse happens as well.  So who knows, right?
