I agree with Sheriton, but would question the distance you are talking about from TX to RX first. That may not be necessary. Never place a wireless system in close proximity to a router, your DMX tranceiver, CD player, Digital recorder, or any other digital device that gives off possible RF. I always suggest investing in a separate case for wireless, even if a soft case. I don't like wireless DMX at all unless absolutely necessary. They are slow and can give erroneous signals to your lights. Run a cable if at all possible.
