A radome is attached to the spy plane's underbelly.
The plane is equipped with sensors, receivers and dish antennas to capture electronic signals. There are two compartments, one on the top and one on the bottom of the plane, that house antennas. The EP-3E is also equipped with an AN/APX-134 radar antenna and a radome, which are located in a specially-modified cargo bay, according to GlobalSecurity.org. The radome is a dome-like shell underneath the plane. It houses the radar antenna and is transparent to radio-frequency radiation.
