USER GUIDE
The GPS-302L-A40 is an active antenna 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. 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 3.8 to 6.0 VDC to
the antenna is required to set up the GPS-302L-A40. (NovAtel GNSS receivers provide the neces-
sary 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
antenna'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. 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.
The integrator of this antenna is responsible for ensuring antenna installation meets all the
overall integrated system requirements.
Refer to Section 307 of
www.faa.gov/documentLibrary/media/Advisory_Circular/
for information about antenna bonding in aircraft applications.
User-supplied o-ring grease can be used to hold the o-ring in the groove during installation.
