I recently found the old B&W TV my family watched at dinner when I was a kid and I thought it would be a fun project to see if I can get it working again. It's a 1970-something Panasonic Orbitel TR-005. It's in great shape and the display seems like it still works. It doesn't even have a coax input though. It just has UHF and VHF antenna connectors. Is it possible to convert the HDMI output of my cable box to an antenna connection? From what I've found so far, it seems I may have to convert from HDMI to RCA to coax to antenna, but I have no idea if this is possible. Thanks for any advice
