You can easily recognize the meaning of 'Antenne' (antenna) from the context. If it is about technology, radio, or reception, the technical device is meant. In connection with insects or animals, it means feelers or antennae. If people are talking about feelings or moods, it means instinct or sensitivity.
Ohne Antenne habe ich hier keinen Handyempfang.
Without an antenna, I have no cell phone reception here.
In the technical sense, an antenna is often 'installiert' (installed), 'ausgerichtet' (aligned), or 'eingestellt' (adjusted). With older devices, you can also 'ausfahren' (extend) or 'einklappen' (fold in) it.

The figurative meaning is almost always used in the fixed expression 'eine (feine/gute) Antenne für etwas haben' (to have a fine/good feel for something). 'Etwas' (something) is in the accusative.
Als Lehrerin hat sie eine feine Antenne für die Probleme ihrer Schüler.
As a teacher, she has a fine feel for her students' problems.
station / sender
'der Sender' and 'die Antenne' both belong to the area of radio, television, or radio technology. A 'Sender' is either a radio or television broadcaster, or a device that sends out signals. An 'Antenne' is the technical device used to send or receive signals. Learners may confuse the words because both have to do with radio waves. In practical terms: the 'Sender' provides the program or signal; the 'Antenne' helps transmit or receive that signal.

After the storm, Paul had to repair the antenna on the roof.
