Exempel på hur man kan använda HALFWAVE i en mening

• Since vertical halfwave dipoles must have their center raised at least a quarter wave above the ground, whereas monopoles must be mounted directly on the ground, the monopoles' radiation patterns are more greatly affected by resistance in the earth, and the radiation pattern with elevation inherently differs.
• Such a polarization controller can for example be obtained by placing on the optical path three rotatable waveplates in cascade: a first quarterwave plate, which is oriented to transform the incident elliptical polarization into linear polarization, a halfwave plate, which transforms this linear polarization into another linear polarization, and a second quarterwave plate, which transforms the other linear polarization into the desired elliptical output polarization.
