Aerospace Antennas

Product description

SETI of SAST possesses an intact capability of  design, simulation, testing and special research and development of antenna. The antennas developed by SETI have widely used in different types of aerospace models, and many new products that have advanced performance and more completed configuration will come into model application phase in succession.
