I have a Passport Diversity 5.8 receiver and a stinger Pro 250w 5.8 AVD Transmitter. I am constantly getting static and at times, total video black out. I've tried moving the transmitter to different locations with the same results. It's being powered off the main battery, a QC8000mAh. Would a separate power source or lobe antennas clear up this issue? I have a 2 axis gimbal. Heres a short video showing the drop out. This is constantly happening. Thanks!
