RDF technology was around in the 30s, hence the loops seen on many 30s twins & bigger. In WW2 the larger aircraft carried the same loops in bubble fairings and the loop was motorised and aligned automatically to give you a relative bearing. Your F4U *could* fit such a device in but would it be worth the extra weight and drag when they could just use a YE beacon? Considering the fact that they would not even put the relatively small YG beacon demodulators in the land based fighters the answer is obviously no (though perhaps that was partly to do with not letting the enemy capture the technology).
