Antenna is the third studio album and the first major label album by the American rock band Cave In. Released in 2003, it was Cave In's first and only album for RCA before they were dropped by the record label and re-signed with Hydra Head. Antenna marked a shift in Cave In's musical style which, while critically praised, was met with distaste from longtime fans. In the midst of such polarization, the band would later return to its previous style, resulting in Perfect Pitch Black in 2005.

Cave In is an American rock band that formed in 1995 in Methuen, Massachusetts. The band's lineup solidified with the 1998 release of Until Your Heart Stops through Hydra Head Records, and their early albums were prominent in the metalcore scene. The band later experimented with other genres, receiving mainstream recognition for their 2003 RCA Records album Antenna and its lead single "Anchor," which had an overall alternative rock style. The group went on hiatus in 2006, later reforming in 2009 with the release of the Planets of Old EP, followed by the White Silence LP in 2011, both of which saw a return to Cave In's earlier and heavier sound.
