Abstract
An optical telescope uses either a mirror or a lens to collect light. The light is then brought to a focus and magnified by an eyepiece. An antenna in some respects can be likened to an optical telescopes lens or mirror, as the antenna collects the radio signals and brings them to a focus at the dipole of the antenna. This signal is then passed along the feed cable to a receiver and amplified.
