Morphology
The term simply names a specific kind of antenna: 'Yagi' refers to a type/model of directional antenna and 'aerial' means an antenna, so together they denote a Yagi-type aerial. This is compositional and non-idiomatic (a regular noun+noun naming pattern), so a B1 learner who knows both constituents would be able to infer the meaning.
Etymology
Yagi aerial is named after the Japanese engineer Hidetsugu Yagi and is an antenna with a long main rod and several short side rods that all point the same way, like a comb guiding radio waves. So a Yagi aerial is used to 'pick up signals' from one direction and get reception from far away.
