    I've been struggling to find out why I had so much interference on my FPV. I'm using an SC2000 camera with a Newer TS351 200mw 5.8Ghz TX http://www.amazon.com/gp/product/B00EFULQNG/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1 running off of my phantom 1.1.1 accessory power. My receiver is a Newer RC800 LCD monitor/DVR. http://www.amazon.com/gp/product/B00HUL961G/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1

    At first I thought the power on the phantom was the culprit so I added an LC filter. Not much help. Then I replaced the rubber duck antennas with IBCrazy BluBeam antennas http://www.amazon.com/gp/product/B00H2W6YE0/ref=oh_details_o07_s00_i00?ie=UTF8&psc=1. A little better.

    I'm running both the LCD DVR and my DJI TX off of a 3S lipo with a regulator to the TX. I tried going back to just batteries on the TX.

    Finally I shut off my DJI Tx and the video cleared right up. If I put my FPV Rx antenna straight out the side and my DJI Tx antenna straight back, the interference is lessened, but it's still basically unusable. With my TX on I can't go more than 30 ft without almost complete video break up. With it off I can go 50 - 60 ft. before any static. The breakup from the Tx interference is very different from the breakup due to distance. Distance seems to slowly add snow, the Tx creates horizontal distortion and lines.

    Has anyone else had this problem. I wouldn't have expected 2.4Ghz to interefere with 5.8Ghz so badly. Do I need to ground something on my DJI Tx? On my FPV Rx?? Could it be a ground loop of some sort since my FPV DVR is mounted to my DJI Tx with a carbon fiber mount (is carbon fiber even conductive?)

    Thanks.

    Solved the problem.. Took off the back cover of the monitor and lined it with aluminum tape. No more interference...
