Where do FPV goggles get their data from

I have read where people say with their FPV goggles they get short range...maybe 100yds. I thought the signal to the goggles came from the Tx. Can't you plug your goggles into the Tx? In my case, I have the Hubsan H906A.

FPV goggles get their signal from the video transmitter (VTX) attached to the camera, not the transmitter. Range depends on the VTX, the power settings, and the antennas on both the VTX and goggles.

Jeff, my Tx has a video out port. Can't that plug in to the video port on goggles (assuming they have one of course)? And, assuming I can't do that, do you know of a real good antenna to use for the goggles?

What that tells us is that there is a video receiver built into the transmitter (since it has a built in screen, that you can also output to a set of goggles) but the camera still has to have a separate VTX, using a separate signal than the one that controls the quadcopter. When you're flying FPV, you've got two separate signals going, one to control the quadcopter (and passing back any telemetry information) and another, separate signal for the video transmission from quadcopter to video receiver. Distance varies for each - the OP was asking about video distance. Someone else here may know whether the VTX inside a Hubsan H906A can be upgraded or has switchable power.

H906a will just tune into any 5.8ghz vtx.
Range depends on the antennas supplied.

Rubber duckers being the worst
Omni the best in my opinion but mid range.
Helicals get the longest range but require head placement. If you got a tracking system then you can't get any better.
Combine the TBS crossfire with a tracking system & diversity. You got 35 miles of fun.
But restricted to planes for that range.
