Driven by economics, it is common to repurpose existing indoor antenna ranges for different applications such as hardware-in-loop (HWiL) testing of systems. If the range was originally intended to have a centered line-of-sight, using it for a different use may create reflected paths with high angles on incidence onto the lateral walls. These reflected paths have angles of incidence onto the absorber that are very large and cause for the absorber to perform poorly. Two different approaches are possible to improve the range performance. One of them is to use a Chebyshev approach. The second approach is to tilt the absorber blocks to change the angle of incidence to the incoming wave. In this paper numerical methods are used to study the difference between the two approaches to see their advantages and disadvantages.
