PURPOSE:To simply and strongly set a parabolic antenna device by saving labor by clamping the weight of a proper weight to the tips of plural foundation legs attached to a base seat to support the pole of the antenna. CONSTITUTION:Four legs 4a, 4b, 4c and 4d are fixed with bolts 3a and nuts 3b to a base seat 3 to which a pole 2 attached with a parabolic antenna 1 is to be fixed. Weights 5, e.g., concrete road sole plates, etc., are attached with U-shaped metal fittings 6 and nuts 7 to the tips of the legs 4a-4d. They can thus be assembled easily in a short time, and the parabolic antenna can be stably set without the needs for overmuch labor and time. |
