Abstract: A variable gain horn and a system for testing an antenna with the variable gain horn is disclosed. The variable gain horn includes a horn adapted to transmit electromagnetic signals to an antenna under test. The horn is adapted to have a diverging lens attached and detached without fasteners at its distal end of the horn by a form fit. When the diverging lens is not attached, the variable gain horn transmit the electromagnetic signals at a higher directivity than when the variable gain horn with the diverging lens attached to the distal end. The system also comprises a parabolic mirror adapted to reflect the electromagnetic signals incident thereon from the variable gain horn to an antenna under test (AUT).
