This Ground Station Operated from a Raspberry Pi-3B and an RTLSDR dongle. The Antennas are both from M2 Antennas. The Rotor System is provided by Portable Rotation. The property is on a decline and the antenna location is south of the main house, so signals are blocked to 30 degrees to the North. Currently there is a pre-Amp on the feed line at the antenna location. The feedline is 50 Feet of LMR400.
