A short-wave therapeutic device is shown for the frequency range of about 10 MHz. to 100 MHz. (3 to 30m. wavelength) which has an inductivity and a capacity of such size that it is adequately in resonance with the frequency used. The device is particularly characterized by the use of a framelike-shaped armature made of a wide strip to provide inductivity which is as small as possible while making the capacity as large as possible by closely superposing the end portions of the armature. |
