NOTE: The gearboxes marked * work with new radiators (such as XN12AF *). The new radiator
has different physical dimensions at the rotary joint and only fits on the new gear box. The slotted
waveguide array radiators are the same as the current ones. The gearing and motors are the
same as those in the former counterpart. Assembled antenna are compatible to each other within
the same for RF output.
