Morphology
The compound's meaning is directly derivable from combining 'dish' (a parabolic reflector for signals) with 'antenna' (a device for receiving/transmitting electromagnetic signals): it refers to an antenna that uses a dish. This noun-noun composition is a regular, cross-linguistically common compounding pattern, so a B1 learner who knows both constituents will readily infer the MWE's meaning.
Etymology
Dish antenna gets its name from its shape: a curved dish like a big bowl that catches signals and sends them to the antenna in the middle. So the name helps you remember it is an antenna that 'receives' and focuses signals from satellites or radios.
