I think the scientists don't think it is worth it.
The reason we need the James Webb telescope in space is because the infrared wavelengths it studies are absorbed by the Earth's atmosphere.
We can observe a lot of the radio spectrum from ground based telescopes

> Since 1965, humans have launched three space-based radio telescopes. The first one, KRT-10, was attached to Salyut 6 orbital space station in 1979. In 1997, Japan sent the second, HALCA. The last one was sent by Russia in 2011 called Spektr-R.

> There have been a few radio telescopes launched into space over the years, most with the purpose of linking with ground-based radio telescopes to form an array with very long baselines (distances between antennas). One such recent project, which ceased operation just a few months ago, is RadioAstron. I don’t believe that there are any currently-operating radio telescopes in space, though.
