Here is a summary of nomenclature of the four related mounts:

702B-1 plus 5A    - Original mount plus system junction box for WECo 233
                    (Pre-JAN WECo commercial designation of AN/ARC-4)
MT-100/ARC-1      - Original mount for RT-18/ARC-1
MT-101/ARC-4 plus - Original mount plus system junction box for RT-19/ARC-4
 J-23/ARC-4                
MT-230*/ARC with  - Mount for RT-18*/ARC-1 and RT-58/ARC-12 (1945)
 CX-181*/ARC-1
MT-230*/ARC with  - Mount for RT-19/ARC-4 (1945)
 CX-182/ARC-4A      (CX-182 eliminates external junction box J-23/ARC-4)

The CX-18# assemblies can not be installed in the earlier MT-100 and MT-101 mounts.
