This probably only has an RF antenna input. First step is to convert the HDMI out of your laptop or Firestick to composite video/audio. This gadget should do the trick and it has a zoom button, which I've found is useful when streaming old TV programs from my Firestick to my vintage TVs.
The second step is to convert that composite video to an RF frequency that your TV can tune in. The cheaper ones use channel 3 and 4, but I've had good luck with agile modulators like this one. This will let you modulate your composite A/V signal onto any channel you like.
If you wanted to get super fancy, you could get several of those "agile" RF modulators, set them to different channels, and combine the RF outputs using a regular RF splitter, then connect you're laptop, Firestick, and maybe a couple off-air ATSC demodulators tuned to classic channels.
Since this is a portable set, you might not want an RF cable pinning you down, so you could look into getting an ultra low power RF transmitter and tune it to whatever channel you want. You'll still need the HDMI to Analog composite converter I linked to above, but you wouldn't need the RF modulator. The transmitter I linked to should get you coverage within you're house and maybe your yard, depending on the transmitter's antenna and placement within your house.
