Try a plastic Owl, Hawk, or other dummy predator mounted on the near the
antenna, but in full view..
It too, may detune things a bit if mounted on it, but at least it'll be
there all the time!...

I imagine full loop voltage between their legs would de-tune them a bit but they just perch one side or the other.
