How to say "antenna" in Japanese

Choosing the right word
  • アンテナJLPT N2approx.Common
    nounThe word for the device that sends or receives radio waves: the antenna of a radio, television, or similar equipment. It is also used figuratively, of sensitivity to information and trends.
    このアンテナを屋根やねにつけると画面がめんがはっきりする。↗
    You'll get a clear picture with this antenna on the roof.
  • 触手しょくしゅCommon
    nounCovers 'antenna' only as a body part: the feelers or tentacles of an animal. It is not the word for a radio or television antenna.
  • 角つのCommon
    nounThe feelers of a snail or similar creature are its つの; the word's core sense is 'horn', so it fits 'antenna' only for such horn-like stalks, never for devices.
    カタツムリがすっと角つのを出だした。↗
    The snail shot out its horns.

Use 「アンテナ」 for the radio or television device and figurative sensitivity to information, 触手 for the feelers or tentacles of animals, and 角 for horn-like feelers such as a snail's.
