Why wouldn't this work?

Can someone tell me why this wouldn't work to provide live air to ground video during freefall?

Haven't tried that particular brand/model...but I'd imagine the bandwidth, if like the units I've tried, won't be enough to provide a clean, useful image. I wonder if they'd allow someone to test one?

Because there's no camera

This is all I found on their site.

"The higher the frequencies, 2.4GHz and 5.8GHz gives us more band width to transmit higher lines of resolution and the video looks more like broadcast quality you would except from your TV."

I'll have to dig into this model a bit more but I abandoned this idea for a couple of reasons a while back. I think that the notion of putting a microwave transmitter next to the head was one component which relegated the mount to the plane. I still think that it would be cool if we could transmit from the plane to a live TV during jump run for the benefit of the folks on the ground, and possibly for some sort of combined edit. The fact that we typically use a leased plane negates a permanent mount. And the fact that I was going to have to dig into my own pockets for the experiment was the killer. Of course the reality that I may not know even the slightest bit about what I'm talking about may have played into it as well.
Might be worth revisiting though.

It does work. I have one of their 5 mile air to ground systems. The video & audio went from a Sony TRV 20 via the A/V mini jack to the wireless transmitter & battery that was in a fanny pack on my waist facing to my front .This is a line of sight system. So I had to make sure that I had the right angle from the transmitter to the receiving antenna on the ground.
I found that it was best to always be facing the receiving antenna.
To help I had someone on the ground monitoring the incoming video and adjusting the receiving antenna to get the best video. I was jumping from 13,000 ft ,

care to post a few seconds of what the receiver output is?

[videointhesky 0]

Yes I would gladly post some of the output video.

All I need to now is to find the Hi-8 tapes that I recorded to. It may be easier to send you the Air to Ground set up and let you try it

Any popular transmitter makes amplitude modulation of a video. In freefall your distance changes and quality depends on an utomatic gain control of the receiver. It works well for static sources. For moving, it creates oscillations in brightness.
Only systems with FM modulation work well. Satelites use this method and TV, potable video links, use FM modulation. Few systems including mine, over 25 years old, that were used in skydiving had FM modulation transmitters.
If the unit shown is FM, than you can try. In skydiving all is in the line of sight. Ask woofos :-)
