From where and how much do they cost?
I bought a modulator off ebay but I'm getting interferance would a digital one be better?

no idea what you mean mate. A modulator takes an analogue signal and "broadcasts" it to an aerial connector at a fixed frequency.

It's very much analogue to analogue, and I don't know how you could use digital.

In all honesty, you're better off avoiding modulators if possible and going for an auxiliary input...
