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. 

• 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

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.
