The MIL-STD-461 standard requires absorption starting from 80MHz. With the HC-50TR absorber, it is possible to meet this standard using only the truncated pyramidal absorber, without the need for ferrite tiles. This provides several benefits, including a reduction in the cost and time required for construction, as fewer materials are needed.
Additionally, the relatively low height of the HC-50TR absorber results in a more efficient use of space inside the chamber, providing more room for testing equipment and personnel.
Overall, the HC-50TR absorber provides a cost-effective solution for meeting the MIL-STD-461 standard in an anechoic chamber.
