ABSTRACT:
An improved high frequency filter in a coaxial construction with one or a plurality of resonators has a thread pitch or thread pitch angle of an external thread of a thread-like tuning element which differs from the thread pitch or the thread pitch angle of the internal thread of the thread receiver at least in a partial portion of the length of the internal thread and/or of the external thread. The difference between the thread pitches or the thread pitch angles between the external thread of the thread-like tuning element and the internal thread of the thread receiver is more than 0.5%, and preferably 1% to 5%.
