Wedge absorber effectively reduces reflections between 30 MHz and 100 GHz and its RF reflectivity levels are the same as its equivalent sized pyramid absorber. Wedge absorbers are used in areas of chambers where pyramid absorbers would provide too much backscatter under specific configurations.

ETS-Lindgren guarantees its EHP absorbent material meets specified standards for material fire retardancy. Wedge absorber can also be provided in transitional parts from one size to another providing a continuous line in the absorber, i.e. a 5 in (12.7 cm) wedge to a 12.3 in (31.1 cm) wedge. These parts are typically 2 ft x 4 ft (61 cm x 121.9 cm) or 2 ft x 6 ft (61 cm x 182.9 cm) long and used in tapered or compact range chambers.
