[ARC5] What the ZBX was?

[zakariya.abu at yandex.com]

I would like to ask if someone knows what the ZBX was? Was it a 
particular type name of the ZB aircraft carrier landing system that 
operated in VHF? If yes, in what dimension: was that the AN/ARR-1 or 
AN/ARR-2?

The ZBX term was used in the Navy's report on the disappearance of 
Flight 19 five TBM Avengers in December 1945 off Florida.
