This is the 3rd Range Test to try and reach 1.5 kilometers. I reached 1093 Meters with good results. I did range testing on the Spektrum DX8 Transmitter and AR8000 Receiver and Remote. I used a Spektrum Flight Log to monitor the control system. At the same time I was testing the Fatshark 600TVL CMOS Camera, 600mw Video Transmitter and ImmersionRC SpiroNet Antenna placement on the F550. And Also the Ground Station, ImmersionRC 5.8ghz DUO Receiver with SpiroNet Antenna and 5.8 GHz SpiroNET Patch Directional CP Antenna mounted on a 73 inch pole. Spektrum Flight Log Results for 1193 meters away: Main Receiver Fades=455, Remote Receiver Fades =265, Frame Losses=117, Holds=0 5.8 GHz SpiroNET Patch Directional CP Antenna (RHCP) Right-hand circular polarization 5.8GHz ISM Band 13dBi gain Beam width 35 degrees (H + V)
