Improvements in the tuning devices for high frequencies that are characterized in making the coil to be tuned by winding the thread on a special hollow core and that has means for its fixation, giving this core a metallic or magnetic piece that is housed in its inside, it moves axially in a controlled manner, thus varying the inductance of the coil as a function of the relative position of the displaceable part inside the coil.
