The retractable antenna could only be used for Morse code. Only Harry Manning was well-versed in Morse, so after he quit, neither Earhard nor Fred Noonan effectively couldn't use it anyway [1].
That retractable antenna was for low frequencies. If you are referring to the underside "V" antenna (which was not retractable), that one was likely just damanged, not intentionally removed. [1, 2]
