The reflection of metal components inside the radome would produce disadvantageous electromagnetic interference for antenna causing serious consequences like the reduction of transmission of radome. An effective method of solving the problem is to pave wave-absorbing materials on radome both internally and externally. The wave-absorbing property of PMI plastic foam is excellent and the weight is light, which reduce the load after using wave-absorbing materials. We provide Vicell PT and Vicell PH series in radome area.
