The Sloper Antenna is a slanted Dipole antenna. While horizontal dipoles required two large support masts, this antenna type only needs one large mast. It is therefore widely used by radio amateurs with limited space. In particular for low frequencies this antenna form is interesting. The angle of the slope is usually between 45°-60° and the lower end of the wire is at least 1/6 wavelength above the electrical ground. The dipole is mostly fed with a coaxial cable in the center. At least 1/4 of the wavelength of feedline must be in 90° angle of the antenna. It is also possible to feed the antenna asymmetrically. Due to the radiation pattern this antenna has a good performance for long distance QSOs (contacts) (DX).
