On My Wavelength

Video Overview
Antennas are the eyes and ears of everything we do, transmitting radio waves to link our cell phones, TVs, and other electronics. These radio waves carry energy through the air between antennas -- sending information like images and voices. Every system operates on its own specific wavelength, so it needs an antenna designed to receive that wave. Engineers at an Air Force research lab in Dayton, Ohio, are designing, building, and testing antennas in many shapes and sizes -- to go on airplanes, inside radios, and even on huge towers. This work is a great example of engineering, says Rey Febo: "putting math and science into something that we will be able to use in our life."
