The 42G1215A-XT-1 is an active GPS antenna that receives the GPS L1 1575.42 MHz frequency, the GLONASS L1 1602 – 1626 MHz frequencies, the GPS L2 1227.60 MHz frequency, the GLONASS L2 1245 – 1260 MHz frequencies and L-Band 1528 – 1556 MHz frequencies.
The 42GOXX16A4-XT-1-1 is aircraft certified for navigation. This guide provides the basic information you need to install and begin using your new antenna.
ADDITIONAL EQUIPMENT REQUIRED
•A device with an antenna input port that both receives the RF signal and provides 2.5 - 24.0 VDC to the antenna is required for the 42GOXX16A4-XT-1-1. NovAtel GNSS receivers provide the necessary power through their antenna RF connectors.
•Coaxial cable with a male TNC connector
INSTALLING THE ANTENNA
Both the input DC power and the output RF signal use a single coaxial cable connected to the antenna's TNC female connector.
The antenna attaches to a surface with an ARINC-743 bolt pattern. Four screws pass through the antenna housing.
To install the antenna:
1.Install the supplied o-ring into the groove on the antenna base.
User supplied o-ring grease can be used to hold the o-ring in the groove during installation.
2.Predrill the mounting holes and the connector clearance hole on the mounting surface. See the Mechanical Drawings section for mounting pattern details.
3.Use the four supplied mounting screws to attach the antenna to the mounting surface. The o-ring com- presses and creates a seal between the surface and the antenna.
NovAtel recommends thread-locker (not included) on the mounting screws.
