Hi Mike,

I was afraid someone would mention that!  Using that would complicate the
number of connectors needed.  I've seen the J-23 in the AN/ARC-4 manual,
but:

1.  Do they really exist in any practical (ie, obtainable) sense, and
2.  Do you suppose they were ever actually used, especially in aircraft with
open wire harnesses?

I know that the various ARC-4 systems in the ARC-5 manual AN 16-30ARC5-2
show no use of a J-23/ARC-4.  For that matter, it doesn't appear that the
also rare J-28/ARC-5  was specified for the VHF ARC-5 installations except
for those with shielded conduit type cables.

There is an error in the ARC-5 manual for the ARC-4 systems shown.  The
C-52/ARC-4 is shown as an alternate control box to the C-51, yet for some
reason the C-52 was designed for an AN-type connector rather than the C-51
PL-153-type connector, and that AN connector is not called out in the system
diagram.
