Which technology in particular are you referring to here? If you mean the capacity to send a signal all the way from the moon back to a control station on earth, I don't doubt that at all. Obviously a trip to the moon would involve a large amount of tech with very narrow use cases that no one would have bothered to develop (because there's no other reason for an antenna system capable of broadcasting over the distances involved, for example). Developing things like that and working out all the issues is hard, so I'm not surprised they had to get someone to build something specifically for the purpose.
