The Mesa Antenna Measurement Facility has three indoor ranges in anechoic chambers. These provide means of assessing antenna performance while protecting the hardware from weather and maintaining a stable temperature environment. One of the chambers has movable walls of absorber permitting reconfiguration for optimal reflection control.
Two of the chambers located in the basement of building 212 are both adjacent to each other and an assembly room which can be used to stage equipment and hardware to be used in the ranges. The assembly room also hosts a service elevator that can be used to lift equipment from ground level to the antenna range level.
Each range also includes a ground level anteroom equipped with mono-rail cranes which also can be used to stage and lift equipment into the range.
