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.

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable ...

ELITE 750 - Broadcasts every radio wavelength—AM,FM, LW, SW, SSB and VHF aircraft band frequencies. The 360° rotating AM antenna pulls in even the weakest of signals for full, bold sound.

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 ...

By leveraging cutting-edge additive manufacturing techniques and shape memory alloys, researchers at the Johns Hopkins ...

The electromagnetic field travels from the antenna in all directions and at the speed of light. It travels until it hits your radio's antenna as well as hundreds of other receiving antennas.
