The research described in this paper is aimed at improving wildlife telemetry systems by means of improving radio frequency (RF) visualization and planning, and improving RF coverage by adoption of improved techniques and tactics. The use of a computer-based modelling application has proved to be of benefit in the area of visualisation and planning. Use of this tool and other work in this area has led to the identification of opportunities to improve field practice, e.g. staff training in RF techniques and tactics, selection of optimum receiver sites, improved receive antenna systems, and improved planning for airborne monitoring and tracking.
