Hi, I fitted my horizon Blackhawk and nimrod antenna , one on each channel and managed to test the range this gusty evening. I found the range was only improved by some 100-200' I have an idea what may be the issue but want to run it past you experts here on the forum. I had the Blackhawk plugged into one channel and the nimrod to the other and flew out to about 1200' the video quality was good but distance not much better. I turned the wifi off re charged it and swapped them around and flew out, the distance was worse about 900' and video quality poor. I couldn't continue anymore as it was going dark. My theory is that possibly one of the aerials wasn't connected properly , possibly the pigtail not clipped on properly and the unit was running purely off one aerial? Is this possible as it would explain why the distance isn't really much better? Thanks in advance.
