You see these three images?
Buy a box TV for retro gaming that is a b / w composite video analog television that only requires a single coaxial cable (strongest frequency for composite video is 15.7 MHz for horizontal sweep frequency, 4.5 MHz for bandwidth and 60 MHz for vertical sweep frequency), get an RF modulator for picking up radio frequencies and make sure you can broadcast video (usually analog channel 3 or 4) and get an antenna with a bit of power boost. But there are low-power allowances for such a 'broadcast'. The amount of frequencies available are channels 3 & 4. Channel 3 spans 60 MHz to 66 MHz and channel 4 spans 66 MHz to 72 MHz. Now the converter output is radio-transmission ready.
The video is modulated in vestigial sideband (like AM modulation, but with a narrowed bandwidth) and the audio becomes an FM signal at the high end of the bandpass. Sync is the highest AM power, black is slightly lower and white is minimal. Stereo sound uses a second subcarrier. So you might need that too, because there is no way the composite (a baseband signal) can go out an antenna to any receiver; it just can't contain any channel 3 characters. Also, not just any TV can pick up your signals and vice versa. BUT, some other-than-TV pickup can be managed called "Van Eck Phreaking". Simply use a Cathode Ray Tube (CRT) TV and learn how to transmit/receive RF signals using CRT. Then you're good to go.
Once you've accomplished all that, you can now use analog TV in 2022 FOR FREE. There's no telling what you'll find on there. Btw, it's illegal to do this. So disregard everything I said olololol.
But in all srsness tho, fuck Digital. I miss analog BECAUSE THERE'S NOTHING ON DIGITAL TO WATCH!
