There are cheap composite NTSC to PAL converters, but these only convert the frequency of the color carrier, so basically get PAL60, which works on many PAL-only composite inputs, but can't be converted back to PAL RF.
You're positive that that TV is RF only ? If it was intended for any computer use, composite seems likely at least.
When I lived in the Uk, I had a converter for my American SNES that allowed it to display a 60hz Pal signal through RF for TVs that could display 60hz but not NTSC or RGB. It also had a 50hz switch. So.... it is possible but whether anyone still makes decent converters is a different story.
It might be easier to convert to an SVideo output and then search for an SVideo to rf adapter.
But.... in a time where people are literally throwing old CRt TVs in the trash, surely it would be better to get one which at least has Svideo... it seems like a silly problem to be trying to solve in 2018.
As an FYI, every Sony crt tv I ever owned was capable of displaying a 60hz signal and all but my 14" (which had RGB) could do both ntsc and pal. But... I never had one from the 80's before every set had composite video and SVideo as a minimum. From memory, very few TVs that only had RF were capable of displaying anything except a 50hz pal signal.
