These guys claim to do it:
Qara CVI is an innovative system for wireless video transmission in HDCVI standard up to 2 km in the free 5.8 GHz band.
The system consists of Qara CVI transmitters (single and dual input) and universal receiver EVIF Multi cooperating with other standards of analog HD technology. It enables transmission of images from CVI cameras to hybrid recorders (CVI, AHD and TVI) as well as recorders with network protocol ONVIF 2.0.
Qara CVI is a solution for easy replacement of analog monitoring in PAL resolution with a new, much better image quality (HD).
• 720p (1280x720)
• 1080p (1920x1080) Full HD.
No idea on how much it costs, or how well or if it even works, but they seem to have a few other products that look real, so worth an inquiry.
Thanks John & Undisclosed 1 - appreciate the input and am glad to hear I'm not that far off track. I'll check out the Qara.
I don't know pricing on the Qara, either, but for reference, analog wireless was historically much more expensive than what you'll get a pair of radios like Ubiquiti for. SD analog transmitter/receiver sets were often over $1,000 each and I would honestly not expect HD analog to be far cheaper, but who knows, it's possible.
This was actually one of the first reasons we started using IP cameras when I was an integrator, because remote cameras, whether wired or wireless, were much easier to install via Ethernet than trying to convert analog and send it back.
Also side note, the Qara unit looks like a CVI encoder on the transmitter side, which sends signal back wirelessly to the receiver which outputs ONVIF. Neat application, but you'll still need IP capability on the recorder.
What would be your cost be to replace the current HD DVR with a hybrid unit which supports IP?
New DVR/NVR plus a UBNT PTP link and IP camera could be your best option and cost less than the wireless option above.
Not an endorsement, but since I came across it, there is an AHD 1.3MP (only) wireless kit from AV-Link.
I also found a company called Ionodes http://www.ionodes.com/ that has lower cost encoders but still about 1200 a set per camera so I think I'm going to stay with IP at the poles, change the DVR out to a Hybrid and use the HD Analog inside.
All the responses have been very helpful - thanks so much!

As Michael said above, get a tribrid DVR instead of just an AHD only DVR. The new Dahua 3.0 recorders will support just about any camera; ONVIF IP, SD Analog, and all three HD Analog, HD-CVI, HD-TVI, AHD. They don't support HD-SDI, but I don't know of many hybrids that do.
With the tribrid, you can then use IP cams at the poles via UBNT wireless backhaul, and AHD everywhere else.
The other option is to place a small DVR at each pole. But, enclosure size is going to get rather large.
I am bumping this since a member just asked the same question. I have not seen any new HD analog wireless systems be replaced but I might have missed it. Anything new?
Maybe I should turn this around. Are there any IP cameras specifically designed for LPR??
Thanks again John
Just LPC. I hope to pair it with PlateSmart for recognition.
Thanks John, I appreciate it.
No endorsement either, I am looking for this as well and this is what I found.
And unfortunately for my project, I need CVI for Illustra line of HD Analogs.
