Cuming Microwave Materials & Anechoic Chambers


Cuming Microwave offers two types of products for antennas, one for antenna testing and the other for antenna pattern shaping.

Antenna Testing

Cuming Microwave offers an extensive line of high performance pyramidal and convoluted absorbers. Materials are designed for use in antenna ranges, anechoic chambers and test boxes. Cuming utilizes state-of-the-art equipment and controls to ensure homogeneity within each piece and lot. This process allows cost effective methods in the production of pyramids, wedges, twisted pyramids and other geometric shapes. All materials are qualified for fire retardancy and are tested 100% for electrical performance.
