USB-UIRT Forum

I need to distribute the IR from my USB-UIRT to several rooms in my house. I have RG-6 coax and Cat5e and Cat6 going to each room. Has anyone ever tried the Xantech INJ94 and CPL94B to distribute IR over RG-6?

Or maybe something else using the existing RG-6 or Cat5e or Cat6 lines?

thanks,
