The idea discone antenna looks exactly like its namesake; a metal disk attached to a metal cone. Of course with the frequencies the RTL software-defined radio deals with, it’s rarely necessary ...
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 ...
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.
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.
