SIEPEL AH Multi-Layer Flat Absorber

AH is a range of flat absorbers consisting of five layers of polyether polyurethane foam with 90% open cells impregnated with a dielectric carbon solution, a binder and a fire retardant.

AH absorbers are used to cover all metal surfaces, masts and antenna bases, and also contribute to coupling reduction between antennas. The high absorption characteristics of AH are obtained with small thicknesses.
