Question Video signal to TV with only "External Antenna" Jack?

Hi all;

I'm a little new to vintage televisions, but would like to know what options might exist to feed an early transistor TV (1970s) with a video signal, if it only has an "external antenna" jack.

In trying to recreate a period-specific display, I need one of these older TVs to be displaying video coming from a computer. I have an older computer that can give me a composite signal from its graphics card (RCA jack), but how do I get that onto the older TV? What can I feed to the external antenna jack?

Many thanks,
Tim

You will need to get a modulator, which will transmit on Ch. 3 or 4. Should be easy to find on the bay.

Ah, thanks Celt... I'll look around. I figured it was something quite straightforward.

Modulator your best bet. Adding jacks doable but not
worth the effort. Gotta be sure its not a "hot" chassis
first but most will be........

Thanks, Zeno. Yes, I was hoping only to feed a signal to the external antenna jack. And a modulator that gives me a CH3/CH4 signal I gather will do the trick.
