With so sensitive to WiFi interferences and both antennas covered with remote box and partly shielded by the phone or tab, I'm assuming moving both of them out maybe a good idea. My concern not about of city landscape, where I can reach near max range figures, my concern is areas where the number of WiFi routers per sq.ft larger then users who are using them 
It's unbranded china DIY set, with 3D printed antenna base and unlimited choice of antennas. Surprisingly the cables are two time thicker then factory one for the great benefit for the signal quality.
Will give it a try tomorrow to try if Strong Signal Interference and video feed will stand the test, standard has failed.
This is the photo of possible challenge, standard leg from holder may bend the cable due to there crossing point. Not my problem as using central stand, but maybe helpful who is considering the upgrade
