Fake Radome
From Command and Conquer Wiki
Due to heavy bombardment from the Soviets the Allies developed fake buildings which were made to deceive enemies into targeting them to draw attention away from their real counterparts. The Fake Radome could be used as a distraction from Soviets trying to knock out Allied radar by destroying their Radome or from Radar Jammers trying to jam it, especialy sense the Soviets had no way of knowing if the Radar Jammer was really jamming it or not. It was not used by GDI or Nod.
