HDMI to Coaxial

[Tomlaw0309]

I want to convert an HDMI Connection back to a Coaxial Antenna connection. I'm not worried about keeping the HD picture but just want to be able to use the existing coaxial cable already in the house to get the picture to a tv upstairs. Is there an adaptor that can do this?

The terms are "hdmi RF modulator." I have zero experience on item so can't suggest a recommendation.

This one sends HDMI over a single coax cable. If doesn't convert to RF so the remote TV has to have an HDMI input. It will give you HD.

or
Use an HDMI to composite video+audio converter to provide an input for an AV RF modulator that will give you a channel 3 or 4 output.
