Antenna Devices
Antenna performance can greatly affect the range and reliability of your product, however these devices are often an afterthought in the process of an RF design. Digi-Key has a large offering of antennas at almost any frequency with multiple style options to best fit your application such as whip antennas, high gain antennas, and chip antennas. Whip styles are also available in various connectorized versions or with cable attached.
