Typical Internal Dimensions:     
Length: ~6.2m (includes test distance and equipment layout)
Width: ~5.4m (accommodates equipment placement)
Height: ~3.6m (accounts for antenna size and absorber installation)
Absorbing Materials: 
Walls/Ceiling: Ferrite tiles + hybrid absorbers (optimized for 30 MHz–18 GHz; extendable to 40 GHz)
Floor: Metallic ground plane (with copper finger stock for electrical continuity)
Shielded Door: 
Electromagnetic shielding door meeting automotive/military shielding efficacy requirements
