 The system was tested over a path distance of 28Km.  During the fight a 20db attenuator was placed in line with the antenna - this simulated a path distance of 280Km and data was received with low loss.   The system was tested over a path distance of 28Km.  During the fight a 20db attenuator was placed in line with the antenna - this simulated a path distance of 280Km and data was received with low loss.
