Claims

[Claims for Utility Model Registration] (1) A pair of parallel beam members having various cross-sectional shapes are connected at their intermediate portions by a plurality of connecting members that are perpendicular to the beam members, and the plurality of connecting members are connected at the upper side thereof. A holding means is provided for rotatably holding the antenna at a set position, and the pair of beam members are arranged on the lower side of both ends thereof,
A structure for an antenna installation frame, characterized in that a stabilizing weight is attached to the antenna to maintain the antenna in a stable state unless a force greater than a set wind pressure acts on the antenna. (2) Three or more beam members having various cross-sectional shapes are combined in a radial shape at a central portion, and a holding means for rotatably holding the antenna is provided above the combined central portion, and the beam member is Antenna installation pedestal, characterized in that a stabilizing weight is attached to the lower side of each of the tips to maintain the antenna in a stable state unless a force greater than a set wind pressure acts on the antenna. structure. (3) The stabilizing weight consists of a plurality of concrete block pieces divided into easy-to-carry sizes, and each of these block pieces has a locking recess and a locking protrusion on the abutting sides that lock both. of the antenna installation frame according to claim 1 or 2 of the utility model registration claim, which is formed with a plurality of blocks and is integrally connected by a connecting bolt inserted through a through hole provided in each block piece. structure. (4) Utility model registration claims 1 to 3, in which the stabilizing weight is prevented from protruding from the surface by a nut member having a female thread formed at the connection part with the beam member. The structure of the antenna installation pedestal according to any one of the above.
