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 Title: Re: Help needed to improve vedio quality and range of 5.8 ghz Post by: ram singh on May 25, 2015, 10:58:49 AM My 900mhz 800mw video tx with stock wip antina on my quad get clear line of sight range is 4km

Title: Re: Help needed to improve vedio quality and range of 5.8 ghz Post by: MKARTIKGANDHI on May 25, 2015, 11:18:59 AM How you set Up your quad with 900mhz ..... I saw lots of videos saying 900mhz is not good inside City limits .... every radio controlled thig CAN interfer with 900 mhz signal ....???
Title: Re: Help needed to improve vedio quality and range of 5.8 ghz Post by: Himadri Roy on May 25, 2015, 02:38:39 PM 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? Title: Re: Help needed to improve vedio quality and range of 5.8 ghz Post by: MKARTIKGANDHI on May 25, 2015, 02:45:10 PM what kind of power lines
regular power line which power houses in a colony or big ones?? yes there are power power lines in near vicinity but still they are atleast 50-100 meters away??? any more suggestions????

Title: Re: Help needed to improve vedio quality and range of 5.8 ghz Post by: MKARTIKGANDHI on May 25, 2015, 02:50:01 PM i will check that how far they should be to each other???
Title: Re: Help needed to improve vedio quality and range of 5.8 ghz Post by: Himadri Roy on May 25, 2015, 02:52:57 PM 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!
