The term antenna was coined by AEGEE and names any local organization group of AEGEE in different cities of Europe, e.g. AEGEE Berlin or Hamburg. At SprachDuo, the term antenna is synonymous with a city in which a user registers to search for language partners. The list of SprachDuo antennas is not the same as all AEGEE antennas. But each antenna of AEGEE is free to use the antennas of SprachDuo as real broadcasting antennas for their own events, to inform the SprachDuo users about international and foreign language events.
