Morphology
The meaning is directly compositional: 'nondirectional' (not directional / receiving from all directions) modifies 'antenna' (device for sending/receiving signals), yielding an antenna that works equally in all directions. This adjective + noun pattern is regular and cross-linguistically common, so a B1 learner who knows the constituent words will readily infer the MWE meaning.
Etymology
Nondirectional antenna is like a lamp in the middle of a room: unlike a directional antenna that points one way, it sends and receives signals the same way all around. So, it means an antenna that works 'in all directions' and covers an area without aiming.
