There are some obvious benefits of having a wireless monitor system, but since I am new to the game I would rather not have spent a fortune on buying one, so I put my electronic skills to good use and I made my own system. For simplicity, I used 2.4ghz, which is a bit of a shame as its such a common frequency the connection can be quite unreliable at times. It always works, but if theres any electronic gizmos near by, especially microwave ovens, you often get stripes on the monitor, but oh well it works well enough.
The system is built into two project boxes, the transmitter is 95x120x30mm and weighs about 300g. It can be powered by a 4pin XLR plug, the other end of the cable plugs into the Lemo connector on the steadicam sled and is powered off the Vlock batteries. If I am not using it on the steadicam, I can also power it using the 2.5mm barrel connector in the top of the transmitter. I can power it with any voltage up to 35v as it has an internal voltage regulator system.
Video input is via a BNC or phono plug. Whichever input plug is not being used can be used as an output for the steadicams monitor. This built in splitter system works weather the transmitter is powered or not.
At the moment the receiver is mounted to a cheap £100 LCD tv that I got from maplin. It will do for the moment, its good enough for the director to read off, since im just doing low profile stuff for experience only at the moment.
Heres a nice photo of the transmitter unit...

The receiver is basically the same thing.
Any input from the pro's would be great, Im still unsure how to mount it down, I tend to tape or clamp it to the rails at the moment...
