Slant +45°

A type 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 is achieved by positioning the internal antenna element at a 45-degree clockwise angle. This orientation corresponds to a 45-degree clockwise slant from a typical horizontal or vertical mount. For efficient communication, particularly in directional point-to-point or bridging antennas, the transmitting wave's polarisation should match the orientation of the receiving antenna. Thus, a +45-degree slant polarised antenna should be aimed at a -45-degree receiver so that the two opposing slants match.
