Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figures 1 to 5, a kind of enhancement mode satellite tv antenna, comprise reflection pot 1, be arranged on reflection pot 1 central point poly-wave duct 2, be located at the tuner 5 at reflection pot 1 back side and be connected to the perflectometer 3 of poly-wave duct 2 front ends, tuner 5 is connected to the rear end of poly-wave duct 2. Between perflectometer 3 and poly-wave duct 2, be connected by dust cover 4, dust cover 4 is bucket-shaped. Wherein, as a kind of improvement of the present utility model, be provided with signal amplifier 7 in tuner 5, the reflecting surface 31 of perflectometer 3 is provided with the convex cone point 32 of the center line formation of self-reflection head 3, and the radius of curvature of cone point 32 is R3 ± 1.5mm. Line between cone point 32 and reflecting surface 31 edges is recessed parabola, and this parabolical radius of curvature is R75mm～100mm.
