ANTENNA GUIDE
The 42G1215A-XT-1 is an active antenna designed to operate at the GPS L1 and L2 frequencies, 1575.42
and 1227.60 MHz. The antenna is aircraft certified for navigation. This guide provides the information
needed to install and use the antenna.
ADDITIONAL EQUIPMENT REQUIRED
• A device with an antenna input port that both receives the RF signal and provides 2.5 to 24.0 VDC to the
antenna is required to set up the 42G1215A-XT-1. (NovAtel GPS 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 flow over a single coaxial cable connected to the unit's
TNC female connector.
The antenna is attached to a surface by means of an ARINC-743 Bolt Pattern. Four screws pass through
the housing of the antenna.
Install the antenna as follows:
1. Place the o-ring into groove on the antenna base (o-ring supplied).
2. Pre-drill the mounting holes and the connector hole on the surface. Refer to the Mechanical Drawings
section of this guide for details on the ARINC-743 mounting pattern.
User-supplied o-ring grease can be used to hold the o-ring in the groove
during installation.
