L2 Band 1.227GHz GPS Internal Chip Antenna

For location systems needing redundancy, the addition of new civilian-use signal is transmitted on a frequency other than the L1 (1.575GHz). The L2C signal is able to improve accuracy of navigation, provides an easy to track signal, and acts as a redundant signal in case of localized interference. Johanson Technology p/n: 1227AT45A0042
