NovAtel offers GPS antennas and cables tailored for use with the OEM4, OEMV, and SSII families of GPS receivers. These accessories provide for both easy installation and optimal operation. However, as the receivers are designed to meet the needs of a wide range of applications, the use of non-NovAtel accessories or a unique installation may be desired. This application note provides information on the standard NovAtel configuration, as well as recommendations for meeting the receiver’s RF input requirements in special cases. In addition, information on obtaining the equipment required for such cases is given.
The purpose of this application note is to discuss the importance of impedance matching. This Application Note will not go into the specific engineering formulas involved with designing a complex RF transmission line network.
