Abstract
The focusing adjustments of the subreflector of an az-el Cassegrainian antenna that use only linear motions have always ended in lateral offsets of the phase centers at the subreflector’s focus points at focused positions, which have resulted in small gain losses. This article describes how lateral offsets at the two focus points were eliminated by tilting the subreflector, resulting in higher radio frequency (RF) efficiencies at all elevation angles rotated from the rigging angle.
