Cable help for wireless hdmi

I just picked that exact box up a week ago, going to some testing with it later this week. Considering the specs, I think it has a lot of promise, but you'll need some additional pieces to make it work in our world. I've already got a Decimator2, so HD-SDI to HDMI isn't a problem. HDMI back to HD-SDI over BNC (since most field monitors don't have HDMI) is one thing, but the AJA HA5 should remedy that problem.
I'm hoping to get into Clairmont in the next few days and do some testing/playing around, I'll be sure to post my findings. Hopefully they'll have a RED I can toy around with...
As for powering the device from your sled, I have a spare AUX PWR cable (the 2-pin hermaphrodite LEMO cable) which I'm going to rewire personally. The device requires 5V @ 3amps, so I've got a 12/24v -> 5v transformer coming in a week or two that will support that kind of power. I plan to just solder it in line with the cable I already have, and then connecting the proper DC power plug on the other end.

I'm hoping to do some tests with it still, I refuse to abandon hope!

I don't think you can switch between 720p and 1080p or i manually. It will decide that for you. Wide mode is for being outside of the same room as the monitor. We hooked up the RED and just walked it around the house going from room to room. Can you think of anyway to boost the signal or get some sort of repeater going?
I meant use the 720p BNC port on the RED?
And yes, I think what James suggests is worth looking into. Once I do my initial tests, I want to crack open the TX box and determine the antenna's capabilities and opportunities for upgrade.

Okay guys, it's just my opinion. But believe me, you or the guys in the video village won't be happy if you come across with that cheap stuff ;-)

I agree with you wholeheartedly about the HDMI connector, but that seems like a small hurdle to leap if it the result is a <$2,000 wireless HD solution. Like I said, Decimator 2 ($500) on my sled and an AJA HA-5 ($500) with the Air Sync HD ($200), and you've officially connected HD-SDI to HD-SDI over BNC. All that's left is building a container on both ends.
Michael has already tested it, and it sounds like movement isn't a problem. The problems to overcome currently are: 1) additional antenna, and 2) power amplification.
#1: Additional antenna.
Inside the AirSync HD, the PCB has 5 MC-card female connectors for antenna: 1 UPLINK and 4 additional receptacles. For this device, they only added an antenna to the UPLINK connector. Even the white papers indicate the other 4 antennas are supported to add signal strength, adding on the OFDM-MIMO device.
#2: power amplification. This, I'll start looking into after I handle the antenna issues.
Moral of the story: this box seems to be using a mere fraction of it's total potential.

I'm giving up on it now and perhaps will revisit in the future. I have an indie starting next week and I think it will cause more headaches than I would like. But it does have potential.
In the short term, another solution would be to take a hdmi extender via cat5 ethernet cable and put that with the receiver closer to the transmitter and run a 25-50 foot run of cat5 to video village.
Good luck Will and keep us posted.
