Comment on NASA's Voyager 1 spacecraft is talking nonsense. Its friends on Earth are worried

Yeah, it’s most definitely not easy. Thankfully though, high frequency devices like that are very small wavelengths and therefore gain can be achieved with decently small antennas. The higher the frequency, the shorter the wavelength, and the shorter the wavelength, the smaller the antenna needed to receive it. Or a big antenna can hear it from further away, since it has a big collection area.
