Morphology
The noun–noun combination is fully compositional: it denotes a beacon that uses radio technology, so its meaning ('a transmitter that helps navigation') is directly derived from 'radio' + 'beacon'. This standard compounding pattern is transparent and cross-linguistically obvious, so a B1 learner who knows both constituents will understand it.
Etymology
Radio beacon comes from the idea of a beacon, which was a bright fire or signal used to guide people, but using radio waves instead of light. Because ships and aircraft can follow its radio signal, the phrase now means 'a radio transmitter that helps ships or aircraft find their way'.
