From local online flee-market got those coupe of things. Man said he bought them ~10 years ago from communication company when they sold-out some of their equipment. He said that he removed some kind of antenna from the mount, but, of course he had no idea what kind of antenna that was. The mount is made very solid, and I think it can easily hold satellite antenna up to 1m. It has possibility to fine-adjust azimuth and elevation. Another item he had no idea what that was. But I think that CCTV camera can be mounted on top of it and then controlled electrically azimuth and elevation.
