been dealing with this for a few weeks now and its driving me insane. built a 5inch freestyle quad, running a rushFPV tank vtx at 400mw, antennas are the ones that came with it which i know is probably not helping. goggles are fat shark attitude v6 with the stock antennas. the weird thing is video is totally solid flying toward me or to my right, but the moment i bank left and fly the far side of my usual spot the picture just goes to garbage. like full static, sometimes full dropout for a second or two. come back the other way and its totally fine.

my first thought was the vtx antenna was getting masked by the battery or the camera but i relocated the antenna to stick out the back and its still happening. im wondering if its a polarization mismatch or something? or maybe the rushFPV tank just has a weak side on its radiation pattern. havent tried swapping antennas yet because i wanted to see if anyone else had seen something similar before i start throwing parts at it

that directional dropout pattern is almost always antenna related in my experience. the stock antennas that come with rush vtx units are honestly pretty hit or miss quality wise, ive seen people test them and find the radiation pattern is weirdly uneven on some units. i would swap both ends before assuming its the vtx itself - put a lollipop or a foxeer lollipop on the quad and try a better omni on the goggle side too. if the problem moves or changes in character thats your answer. if it stays exactly the same then maybe look at the vtx itself or even RF interference from something at that location.

also worth checking - is there anything at that end of your flying site that could be causing interference? ive had a spot where flying near the parking lot of a shopping center would cause dropouts because of all the wireless junk in the area

could also just be a bad solder joint on the antenna connector honestly. ive had a quad that did somthing similar and it turned out the ufl connector on the vtx was barely making contact, slight flex in the frame at certain orientations was intermittently breaking the connection. worth giving it a close look with a magnifier before you buy anything
