I emailed Brooks about this off-forum, but for other's info, I've pasted it below - a very quick rundown of how I've found the system so far...any questions I'm happy to answer.
I'll start off by saying that I love it. It has a good range. Within 80 metres it does really well. Outside of that, digital break-up starts, where the odd small square here and there doesn't arrive. This does also occasionally happen when you're in closer range but is not a regular occurance. Just yesterday I had it on a RED inside a set built in a studio. Video village was through 2 woodens walls, about 20 metres away, and it worked fine, just the occasional glitch.
The biggest selling point for me is that it is full uncompressed HD-SDI, so the signal outputted is identical to if a cable was hardwired from the sled to video village. At the receiver, it also automatically changes channel, if you change the TX the RX automatically senses it. Also another great feature is that it simultaneously downconverts at the RX. So as well as outputting HD-SDI, it can also output a composite at the same time - ideal for continuity and other people who may have clamshells and other SD monitors.
I have used this for live events on 66metre screens, and the quality is fantastic.
I have also used it on an SR3, SR2 and an ST. No problems at all. Composite standard def transmits just as well as HD. It tends to look dirtier, but that's the difference between composite and HD-SDI I guess.
Surface area of the TX is a bit of problem sometimes. It's very light but it is quite wide and flat. Velcro is OK but it often needs tape to hold it in place too. I didn't get a v-lock battery plate version as I operate with so many different cameras, so I opted to save weight and do it in that way.
Power input is a 4-pin hirose. BNC connectors are for HD-SDI / SDI and composite. There are component connectors on phono / RCA connectors, and also audio can be sent on mini 5-pin XLR. There is also a 12-pin hirose which can be used for data for racking video and broadcast cameras.
