STRUCTURE FOR FITTING SUPPORT ARM OF PARABOLA ANTENNA

摘要

PROBLEM TO BE SOLVED: To obtain a fitting mechanism satisfactory in antenna performance, low in cost and easy in handling by providing upper and lower positioning projections extending respectively inward at the upper and lower parts of a bent part, engaging the end surface of the base end of a support arm with the lower projection of a mount, fitting the hole of the support arm to the upper projection and fixing the mount and the support arm by a connector. ;SOLUTION: The base end of the support arm 5 is fitted to the mount 4 fixed to the rear surface of a parabola reflecting mirror 2, a converter 1 provided with an initial radiator is provided at the tip of the support arm 5 and the mount 4 is provided at the tip of a supporter 3 fitted to the handrail, etc., of a veranda. The notch of the arm 5 is engaged with the lower projection 8 and the hole 9 of the arm 5 is fitted to the upper projection 7, then the mount 4 and the arm 5 are screwed with a bolt 11. The notch of the arm 5 and the engaging of the projection 8 regulates the axial direction of the arm 5, and a hole 9 and the projection 7 regulate the axial rotation of the arm 5.;COPYRIGHT: (C)1999,JPO
