FIELD: construction engineering. SUBSTANCE: this is principally intended for increasing radius of reliable reception and transmission of television and radio programs and it is preferably used in separate scarcely populated areas and zones which can be subjected to earthquakes. Tower-support can be made displaceable and practically of unlimited height. Tower-support has foundation, lattice-type metal body and aerial part. Base structure is made in the form of service building. Located in one of stories of building are four reversible winches. Attached to drums of winches are ropes. Upper ends of ropes are secured to fastening band which surrounds vacuum chamber of tower-support for accommodation of instruments. Vacuum chamber is rigidly connected to main shell of tower-support. Inner space of shell is filled with helium distributed in small packages. Additional shells filled with helium are located in upper part of tower-support. Installed in surfaces of all tower-support shells are electric heaters, aerials and dipoles which can receive and transmit not less than 50 channels. Grounding is effected by ropes which are of combination type. They are steel with external kapron sheathing. Braces with luminaires are arranged over entire length of ropes. EFFECT: higher efficiency. 3 cl, 6 dwg
