Continuing with the direction the band started with on "Creative Eclipses" and "Jupiter", "Antenna" further emphasized spacey, progressive rock tendencies with soaring anthems and clean, melodic vocals while minimising the heavy metal elements that were prominent in their first recordings. Guitarist Adam McGrath attributed the musical shift to both physical and creative limitations; physically, the singer Stephen Brodsky had alleged concerns over the long-term effects of performing harsh metal vocals. Creatively, Cave In had also grown tired of being pigeonholed within the metalcore genre and being forced to consistently perform amongst such acts. On a much greater budget, "Antenna" was also given three months of fundamental recording time in contrast to the four days for "Jupiter" and took a total of six months.
