The composite to RF box is a powered one, an RCA.
The HDMI to composite cable is an eBay special, which I tested on a newer flatscreen with my MacBook as the source but was a no-go.

You need a HDMI to composite
BOX NOT a cable. Those cables are for non-standard HDMI devices.... Basically some early HDMI videogame consoles that wanted to retain composite/component output but wanted only one AV/output connector and thus designed their systems to put composite AV out over the HDMI cable (which was a custom non-standard design)...that cable will only output composite with the specific game console it was made for.
99% of HDMI sources need a HDMI to AV converter box to get valid composite video output...the box contains electronics to handshake with HDCP, decode the HDMIs digital data into AV down scale the video signal and convert it all to analog.
