Frequently Asked Questions
What frequency range does the 36in absorber cover?
The 36in absorber provides our best low-frequency performance, with effective absorption starting from 30 MHz—ideal for full broadband anechoic chambers covering VHF through millimeter wave.
Is the 36in absorber in stock?
The 36in absorber is a special order item. Contact us for lead times and availability.
Why would I need a 36in absorber?
The 36in absorber is necessary for testing at frequencies below 100 MHz, including military VHF communications, broadcast equipment, and full-spectrum EMC compliance testing.
What are dB Absorber pyramidal absorbers made of?
Our absorbers are made of carbon and fire retardant chemical loaded polyurethane foam, volumetrically loaded for consistent electromagnetic properties throughout the material.
Are your absorbers fire rated?
Yes, all our absorbers are certified to NRL 8093 Tests 1, 2 & 3 fire safety standards. Optional test data is available for UL94 and DIN 4102-B2 compliance.
What is the operating temperature range?
Our absorbers operate from -85°F to 176°F (-50°C to +80°C), suitable for standard indoor testing environments.
