Yes, these are all types of radiolinks (and satellite links), with a focused and directional transmission beam. Assuming the normative deviation of the mast from the vertical by 1:100 height, the height of the mast 30 meters - the displacement of the top thus reaches 30 cm. Over a dozen kilometers of transmission, this gives a multi-hundred-meter antenna bifurcation. One technique for combating this unfavorable phenomenon is the installation of a torsional bracing crown at the top of the mast. In the AluPro product catalog in the mast accessories section you can find such a construction.
