The MN-20 loops were used with the MN-26, and
also the RA-10 receiver when fitted with the
loop adapter. There was also a larger diameter
loop, the MN-24.

It was usually controlled by an MN-52 control box,
which had a crank and azimuth dial, but there were
a number of different suffix letters denoting
various small differences in applications.
It is turned by the same MC-124 shaft that is
used for tuning the RU, ARB, Bendix MN-26 and RA-10
etc.

Fair Radio still lists some 20" shafts, as well as
the manual tuning knob, and some accessories.
