Overview
Enviro Forest advanced multi-band directional antenna system with precision control antenna rotary table for direction finding and positioning of interference sources, through the rotary table controller or directly through the instrument control antenna rotary table rotation, effectively improve the accuracy of direction finding and work efficiency. The antenna turntable supports two types of mounting methods: magnetic base and tripod, which are suitable for covert investigation by car and rapid deployment of high-precision direction finding respectively. Dellit’s PC-based mobile positioning and navigation software direction finding mode can effectively reduce the errors caused by the complex electromagnetic environment and provide more accurate direction finding results.
