From the Cheapskate: A must-have for wire-cutters, this paper-thin antenna can really pull down the native channels. Plus: a unbelievable instructional app bundle!

In addition to this discipline, the antenna exhibits a magnetic area that’s the sum of the magnetic fields of all the free moving electrons. The antenna additionally has a dynamic electrical discipline that’s the vector sum of the dynamic electric fields of all the free electrons. What we will do is separate the electrical subject of the antenna at any level in area into two elements. One of many parts can be in part with the overall magnetic field and the opposite can be 90 degrees out of phase. The in-phase component is the radiation subject of the antenna and the out of phase part is the induction discipline. At the antenna, each fields are parallel to the metal floor.
