Low-cost reference station antenna choking coil

The embodiment of the utility model discloses a low-cost reference station antenna choking coil which comprises a base arranged in the center and five concentric choking rings sequentially arranged on the periphery of the base, and five concentric circle grooves are formed among the base and the five choking rings. The height of the choke ring is gradually reduced from inside to outside, and the choke ring is in a pyramid shape. The outer edges of the tops of the four choking rings are on the same straight line; the choke ring and the base are made of plastic materials, and the surfaces are electroplated with metal layers. According to the utility model, the plastic material is integrally electroplated after injection molding to replace a metal choking coil, so that the cost and the weight are reduced, the installation of the measuring antenna is facilitated, and the product competitiveness of the measuring antenna is improved. 本实用新型实施例公开了一种低成本基准站天线扼流圈，包括设于中心的基座以及依次设于基座外围的5圈同心的扼流环，基座、5个扼流环之间形成5个同心圆槽；所述扼流环的高度由
