Spine Antenna Pointing Mechanism (APM)
MMA’s Spine APM™ uses a stack of pivoting vertebra elements forming a spine. The cross-section has a hole in the center, similar to the spinal cord in the backbone, where a flexible RF coaxial cable or wave guide is routed. The curvature of the spine assembly is shallow and repeatable, thus minimizing the bend radius of the FR coaxial cable or wave guide. This approach eliminates complex rotary joints and their associated RF losses, and multiple units can be ganged together to form an antenna array.
