t5 lighting internal ballast

I have read about many digital ballasts putting out a signal that interferes with radio and cable signals. But does the t5 lighting do the same? They list having an internal ballast but not sure if it runs the same as the external ones, Can it cause problems with close neighbors. I'm looking at getting a 4' 6bulb set up for my 4x2x5 grow tent.
