Built to the very highest standards, the Model 100 is the standard version of the positioner from the All Weather Antenna Positioner family. It has been designed to operate with reflectors of up to 2m in diameter. The positioner can cover 'whole sky' and can be used for surveillance, tracking and SIGINT as well as other signal/tracking purposes.

The requirements are valid both for isotropic and uniaxial materials, the latter defined by material properties that are invariant under a rotation about a principal axis. Using asymptotic requirements at zero frequency and Foster’s reactance theorem, the general band-gap structure is given for low-loss materials. It is shown that such materials can only be achieved if the material exhibits finite band-gaps separating regions of positive and/or negative refractive index regions. In degenerate cases the band gaps shrink to zero but low-loss propagation remains impossible in the neighbourhood of the critical frequencies. The effect of small losses are considered, and compared with Stockman’s criterion. Losses may be arbitrarily small within a band provided there are no bounds to the size of the real parts of the relative permittivity and permeability at the band edges. A numerical example is given showing the effect of small losses.
