> Isn't that weird and interesting? I think it's very neat! There's calculators online to design your own QFH antennas and they're popular for amateur use to e.g. receive images from weather satellites. And the calculators can tell you that if you make it more squat, it's more directional. But I don't think anyone had had the idea before to let you vary those parameters by pinning/scissoring it.
