Slant Polarisation (-45°)

A form of linear polarisation where the electric field vector of an electromagnetic wave oscillates at a -45-degree angle, relative to the ordinary mounting of the antenna radome, when viewed in the direction of wave propagation. This configuration is achieved by positioning the internal antenna element at a 45-degree counterclockwise angle. This orientation corresponds to a 45-degree counterclockwise slant from a typical horizontal or vertical mount. For efficient communication, especially with directional antennas, the polarisation of the transmitting wave should match the orientation of the receiving antenna. Therefore, a -45-degree slant polarised antenna is ideally aimed at a +45-degree receiver.
