can i use this transmitter-receiver system to transfer live video for live mixing it blames that it transmits in 500 meter range.Or how can i do this with little money?

I have one of these mounted on a small radio-controlled helicopter:

900MHz 500mW audio/video transmitter [TX-900-500] : RangeVideo!, Wireless video solutions. (http://www.rangevideo.com/index.php?main_page=product_info&cPath=35_21&products_id=24)

And this is the receiver:

900MHz standard receiver [RX-900-standard] : RangeVideo!, Wireless video solutions. (http://www.rangevideo.com/index.php?main_page=product_info&cPath=35_21&products_id=25)


It's ok for monitoring, but I wouldn't rely on it for an actual recorded signal unless there were no other options.
