converter box HDMI to Coax

[laurielp1]

I have an older tvthat has a coax in and a new blueRay player that has hdmi out. Is there a converter that can make these compatible? (hdmi in/coax out?)

Coax in could mean two things. If you mean a yellow video and L/R audio input then you could use a converter like this:

If you mean an antenna connection you would have to add one of these as well:
