   How to Build a Dual-Band Antenna for 2M/70cm. Rubber Ducks are Kinda Like Rubber Chickens. Rubber duck nearly an isotropic source, but not as good. Victim’s head absorbs some of the RF (maybe that explains a few things...) Capacitance to body makes a “sortaground” that supplies half of the antenna plus a decent dummy load.
