I am using st360 quad for fpv but unable to get GOOD range or video flikkers a lot after 200 meters .....see pics ....

Mountung info .....
Video tx is rear side of quade using two cameras with video switcher one is mobius and other one is board fpv Camera .... both antennas are in straight Up position .....Made a diy cheap fpv goggle and attached receiver to it .... I am using different power sources to power motor and video tx.... 


But still CAN not figure out what is wrong with video quality and range .... MY boscam 400mw syatem is in. GOOD condition ...never switched it ON without antenna ....till now I didn't even crossed 6 story Building hight but ....video signal gets flikery. ... does Mobile towers are the cause? ??   PLEASE all quad fpv flyers who did long range flying with quad Help me out here .......I don't know were to look for the fault or how to correct video reception ....will placing video receiver little higher and give a seperation between 2.4 ghz transmitter and 5.8 ghz will Help or not ..... I have no clue what is going ON with range by tx capacity I read everywhere that it shoud give atleast 1 km of cristal clear video signal but that is not happening

I also did a groud range test with it ... groud range was GOOD .... more then 500 meters but Up in air with quad not SO GOOD video reception??? What should I check for


And I want to know how ferrite ring CAN Help to improve signal ...don't know how and where to use them

Stay away from 900 Mhz if are flying in city areas as a Mobile repeater tower can knock your signal down...
Are you powering you fpv gear with the same battery?
If yes are you using a LC filter?

If no, is your video feed line near the power line?

Try to keep them as away as you can from each other or if there is a metallic substance between them even that would do!
