Considering how many ways there is to pump up noise, jammers, wireless negating paint, trees, rain, distance, environment, etc etc. I don't think antennae is the straw that broke the camel's back just yet. Though if they keep adding more noise mitigation is later books, we might start to see some weirdness. But then again the stay at home decker is a tried and true trope of the shadows, so maybe it wouldn't be such a bad thing.
