I've recently started doing some live broadcast jobs using my Cmotion Cpro and RF motor. I'm using the Arri K2.0002007 antenna on my Cmotion RF motor, and i've found that has helped in increasing the range. There have been some scenarios where in the live environment, the camera I'm focusing for has moved slightly out of range for my Cmotion.

I'm aware that x2 Camins can be turned into a range extender. Are there any more affordable solutions?
