Morphology
The meaning of 'radio antenna' is directly and compositionally derived from 'radio' (broadcasting electromagnetic waves) + 'antenna' (device for transmitting/receiving signals); a B1 learner who knows both words can infer it is an aerial/device for radio signals. This noun+noun composition is common cross-linguistically and follows standard English compounding patterns, so the phrase is immediately comprehensible from its parts.
Etymology
Radio antenna may come from the long feelers of insects, called antennae, because early metal rods and wires looked like thin feelers that reach out into the air. So a radio antenna is the long device that 'picks up' radio 'signals' for a receiver.
