In the typical setting, a purported omnidirectional recieving wire does not perform similarly well in every single conceivable bearing in three-dimensional (3D) space. Such a gadget, which can exist just in principle however can be drawn nearer by and by, is called an isotropic radio wire or isotropic radiator.
Reception apparatuses that offer upgraded execution in a few bearings, to the detriment of different headings, are called directional recieving wires or directional radiators.
