[Boatanchors] Motorola maybe antenna loading coils ?

[Glen Zook via Boatanchors]

Those are low band (30 MHz to 50 MHz) base loading coils used on the the various Motorola H21, P21, H31, and P31 from the "A"  versions through the BAC and BAT models which had a solid state receiver and transmitter using pencil tubes except for the final amplifier in the 31 series.  They would work on the solid state low band P series but were not the ones usually supplied.

Those loading coils were also used on motorcycle FM units during the same period as the portable units were being made.
