I had this plane with awful antenna static for days. Was ready to replace the whole unit, which would have been a pain. Then I noticed a shiny bit of foil wedged in the antenna mount. Once I pulled it out, the static was completely gone. Such a dumb fix but it saved me hours, lmao.
Sometimes a simple physical fix is the right call. Checking connections is good, but that foil was clearly the problem. Calling it dumb misses the point of a working solution.
