What I am getting from you is that although I am watching TV channel 3.1 on my tv (virtual), the real tv channel is 46. Therefore when looking for an antennae, I don't need one for channel 3.1 but for channel 46. In other words the antennae receives the real channel, not virtual channel. When I turn the tv channel to 3.1 I am actually receiving channel 46.
