ANTENNA GUIDE
The 42G1215A-XT-1-3 and 42G1215A-XT-1-2 are active antennas designed to operate at the GPS L1 and
L2 frequencies, 1575.42 and 1227.60 MHz and across the L-Band from 1525 to 1560 MHz. The antennas
are 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-1-3 and 42G1215A-XT-1-2. (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 the 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.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
