Size is important, but the correct size for the TV-frequency band is most important. The simplest antenna is a half-wave ...

A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...

Meaning "two poles," a dipole antenna is the simplest type of antenna, consisting of an electrically conducting wire or rod one half the length of the maximum desired wavelength. The wire or rod is ...

Monitoring precession: The researchers measured the electron electric dipole moment in hafnium fluoride ions confined within an ion trap. (Courtesy: Casey Cass/University of Colorado) One way to look ...

New research by an international team of scientists explains what's behind a stalled trend in Arctic Ocean sea ice loss since 2007. The findings indicate that stronger declines in sea ice will occur ...
