Broadcast quality wireless

There are many systems out there which allow wireless triax operation, and allow the vision guys control over the camera on a wireless link. However, these systems (analogue, digital and now HD versions are arriving) are not practical for operators to own, in terms of price tag and systems/camera compatability and are the responsibility of the broadcaster or facilities company to provide. Moreover, their application is restricted by budget - are you talking about corporate live events and non broadcast work, or are you talking about large scale broadcast events?
There are microwave links out there, such as Cam-Wave and the-boxx, which whilst affordable and are stable digital links, both operate with a 12 frame delay, rendering them hard work for a multicamera mix or sync with sound. They are good for single camera live work and ENG etc, and good for all the other stuff, if you delay audio to match video with a Behringer unit. These digital systems, as opposed to our usual analogue systems, work by constantly selecting the strongest signal at the receiver, i.e. Multipathing.
There are wireless triax systems out there from Gigawave, Link Research, Thomson/Grass Valley, and others. These are all usually integrated as part of the truck's camera kit. They work extremely well, and are the norm for most Steadicam applications nowadays on OBs. Antennae are getting smaller, cameras are getting lighter, range is increasing and line of sight is no longer as much a neccessity as before.
The solution is to always talk with your client before the job, so they can get you the kit you need, or as best they can, before the job. Triax & fibre will always be around for us to deal with, but the wireless links out there are getting better and more reliable as time goes by. The wireless links are an incredible innovation that has been, and continues to be, developed, and provides broadcasters with more and more incredible shots, both from Steadicam and from various other means of tracking and moving the camera, allowing us to pull off shots and get angles which were previously impossible to achieve.

Not sure where in the world you are but the ones mentioned by Jason are the standard BROADCAST, not monitoring quality units used in Europe.

I'm looking for info on a broadcast quaility wireless set up that will allow me to eliminate triax on multi camera shoots. Any suggestions?
Hector is using a wireless HD configuration on NBC's :Dancing with the Stars" It is a fully controlled digital system. Along with this years improvements there is an addition to a the wireless , an analog return video feed. They have gotten it to be a very nice compact package. AVS is the owner and as the others have said very cost prohibitive to own if possible at all, but very rentable . . .Sorry I don't have the web site for you.

It all depends on your studio rig and cameras you are currently using, or will be using. Without knowing any more info about the equipment or your location, it's more difficult to make suggestions. Here in the UK, LinkXP and D-Cam Clip-On are very popular, you might want to look at these systems, amongst the others.
Sorry for the lack of info...I'm new to the forum. I work out of Philadelphia, PA, USA and run an Archer for three nightly live studio productions. The company owns the rig and is looking to go wireless so we can use it to shoot sporting events and an other large production that may come about. We are currently using a Sony D35 with a triax back.

I would ask them to take a look at Gigawave - www.gigawave.com. They manufacture a wireless dockable triax back which should dock onto the D35, called D-Cam. The triax cable runs out of the CCU to the Gigawave antenna, which you would need to rig up on a stand somewhere in your studio, and that provides the wireless link to the D-Cam back.
I have a D30 and haven't had the opportunity to use one of these backs with my camera, but I know they are used a lot with the D50's. You shouldn't have any problems at all with this system - very reliable and has been used all over the world, mainly on sporting events and concerts etc.
Hope this helps.

Gigiwave makes a great product. You can rent one of thier microwave system with a 1.5 frame delay from Total RF. I had a month rental from them and the system was rock solid. I did have a transmitter go down and I had one in Orlando the next morning by 8am, great service ! They are in you PA as well. The system will run you about $1000 a day but its the way to go.
I think the camera in the picture is a Sony D-30
