When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.

Modern ham radio operators often face restrictions on antennas. This has made small antennas more popular, despite some limitations. [Tech Minds] reviews the GA-450 indoor active HF loop antenna ...

The system of radio antennas on Earth helps the agency communicate with Voyager 1 and its twin probe, Voyager 2, as well as other spacecraft exploring our solar system. Voyager 1 then sends back ...

Antennas are mechanical components which either transmit or receive radio frequency signals. For transmission, an oscillating RF electrical current is fed to the antenna's terminals, where the conduit ...
