Are there any video upscalers with RF

is there an video upscaler on the market like the framemeister that allows you to hook up an rf connection?

For RF the only thing I could think that would work would be an old VCR, but it would only upscale to SVIDEO or AV

I wouldn't bother buying an upscaler to work with RF - I can't imagine the results being very nice. I think you're better to look at replacing the source signal from RF to something else and then adding an upscaler after that.

What console are you trying to upscale?
