PURPOSE:To toughen the foundation of antenna installation by a method in which a base seat to be fitted with the struts of an antenna is fixed to piles driven under the ground in such a way as to shorten the period of construction by saving labor for excavation and concrete mixing. CONSTITUTION:Two upwardly bent portions with temporary clamp holes are provided on the four corners of a base seat 2 to which a pole 3 fitted with a parabolic antenna 1 is to be attached. The bent potions are contacted with the inner surfaces of piles 6 of an L-shaped cross section, the piles 6 are held by spacers 5 of an L-shaped form, and the bent portions and the spacers 5 are temporarily clamped by bolts, etc., through the temporary clamp holes. Four piles 6 are vertically driven into the ground to a given depth while inspecting the verticality of the pole 3 and finally clamped with the bolts 10, etc. The antenna 1 is then set up. |
