RTL-SDR and SIGINT
The photo at left shows a 2.GHz panel Yagi (a directional antenna) that was installed on a field expedient 30-foot wooden pole that is stabilized with guy wires. It is for use with a RTL-SDR dongle and a laptop to detect the signals controllng the movement of line of sight (LOS) drones that would emanate from the direction of the most likely avenue of approach. Its range of detection would be greatest when placed above the top of trees. In the world of radio, ‘Height is might’.)
The link to the RTL SDR dongle and the software for the RTL SDR, that can be downloaded for free, can be found at the manufacturer’s website.
A communications station in a bucket can be used as a part of a remote station located on key terrain (a hill) that overlooks the area and can be used for Signals Intelligence (SIGINT). This will likely be the most valuable intelligence collection method in the future, and it would be wise to learn how to develop intelligence to the best of our ability, as opposed to simply collecting information, or simply maintaining visual situational awareness. The process involves asking the most pertinent questions and using signal interception as a means to answer the questions posed.Continue reading“A Low Power Communications Station in a Bucket – Part 5, by Tunnel Rabbit”
