摘要: A shield for a satellite earth station located in dense radio frequency environment. The includes antenna position pit. Surrounding the pit is tear-shaped earthen berm. Positioned on top of berm wall made series modular precast concrete panels specially designed to reduce diffraction interference over and minimize internal reflection interference. each include an inner face two sets horizontal slats set at alternating angles. are attenuate disperse range communication downlink uplink frequencies. In addition, present invention shaped grooves cast into which passing wall.
