PROBLEM TO BE SOLVED: To provide a parabolic antenna support enabling the parabolic antenna to receive radio waves transmitted from a horizontal direction by using an offset parabolic antenna which is conventionally used. SOLUTION: The support is provided with a base 61, a fixing plate 60, and holding plates 3 for a pole 50 which is mounted on the fixing plate 61 so as to be able to be pressed by fastening operations of bolts 4a. The lower portion of the plate 60 is fitted on a fitting point provided on the lower portion of the base 61 so that the base 61 can move freely, long grooves 64 being long in the moving direction are provided on the upper portion of the base 61, and a bolt 65 for preventing the fixing plate from moving is provided in each of the long grooves 61 from the base 51 side. Further, the base 61 is provided with an antenna pole 2 which is held by the base 61, and the pole 2 is formed so that an angle between an axial line of an antenna mounting portion 2a being an open end of the pole 2 and a line perpendicular to the plane formed by the base 61 is 40-60°.
