I was given an old dji phantom 2 and I HAVE NO IDEA WHAT TO DO ABOUT THIS FPV SETUP. I have a flysight monitor and i attached the tx to the drone and the rx to the monitor and i still get bad preview within 100 meters of me. Do I need to buy another 5.8 ghz antenna for my drone for a better signal? I do have two spots for antennas on my monitor but one is currently no being used. SOMEONE PLEASE GIVE ME SOME KNOWLEDGE.
