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 ...

ANGOLA, N.Y., Nov. 19, 2025 (GLOBE NEWSWIRE) -- TX RX Systems is introducing a refreshed line of dipole and stacked dipole array antennas designed for customers who depend on reliable communication in ...

It’s a skill that radio amateurs pick up over years but which it sometimes comes as a surprise to find that is not shared by everyone, the ability to casually glance at an antenna on a mast or a ...

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 ...

Using wideband technology high frequency communications can offer commensurate or increased data throughput over satellite communications in normal or satellite-denied environments to augment command ...

Combining gallium and indium, Dr. Michael Dickey, assistant professor of chemical and biomolecular engineering at NC State, has created a material that he is testing for an antenna that self-heals ...

Full-sized EMI antennas can be relatively large and expensive, so the question many companies that want to bring radiated emissions pre-compliance testing in-house ask is, “Isn’t there something ...

A dipole antenna using antenna traps is desired which is to be used to transmit a 140 MHz signal and a 90 MHz signal. Design the antenna assuming a velocity factor of 0.90. First find the wavelengths ...
