If you are rusty on the basic physics of why an antenna radiates, have a look at the very nice animations from [Learn Engineering] below. The video starts with a little history. Then it talks ...

Dr. Sarbmeet Kanwal plans to discuss how the Horn Antenna in Holmdel led to the Big Bang theory at a talk at the county library's Holmdel branch.

Although you might not think of them in this way, you are in possession of two extraordinary antennas, perfectly tuned to receive a narrow band of electromagnetic radiation. These antennas are not ...

They checked everything to rule out the source of the excess radiation. They pointed the antenna right at New York City -- it wasn't urban interference. It wasn't radiation from our galaxy or ...
