Hi, would it be possible to connect a 3.5 mm jack with a rca audio/video cable to the ext ant port on my old crt t.v.? Can this be used to get cable on my old tv?

That is the purpose of an RF modulator. It creates a TV signal like would be delivered from a broadcast TV channel. The coax output of the RF modulator would go to the antenna port on the TV.
 
I wager it needs a RF analog input.

Just about everywhere, u didn't disclose where u are from, OTA (antenna) signals is been converted to digital, so for this to work, u will need an ATSC converter, and if the station(s) broadcast in HD (high definition) the image will look crap.

If u want hook up to your existing cable provider, look for a Video Out on the set-top box, then add a RF Modulator.

Your original question asked about red/white/yellow RCA connectivity. If that is still your question, then NO you can't make an adapter. You have to convert the RCA signals to radio signals (what the RF modulator does). You can't make one of those.

I don't know of an easy way to do so. I guess you could solder the center conductor to the middle of a 3.5mm plug and the shield to the other conductor. But soldering coax is difficult since you tend to melt the insulation around the center conductor. Is it possible. If you have good soldering skills, I suppose so. Or you could spend $3 on the correct adapter.
