GPS-301

GM-14915156 Rev 2 March 2018

USER GUIDE

The GPS-301 antenna is designed for airborne use, but it will operate in any mobile application.

The GPS-301 is an active GPS antenna, 89.6 mm (3.53”) in diameter, and designed to operate at the GPS

L1 frequency of 1575.42 MHz. Its mechanical configuration is a spherical radius molded radome which

provides enhanced protection against rain and ice. This antenna includes the following:

• internal 26 dB low noise amplifier

ADDITIONAL EQUIPMENT REQUIRED

• A device with an antenna input port that both receives the RF signal and provides 3.8 to 8.0 VDC to

the antenna is required to set up the GPS-301. (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 flow over a single coaxial cable that is connected to the

antenna’s TNC female connector.

The antenna can be attached to a surface by means of a square, 4 bolt, 1.9 inch space mounting pattern

as shown in the Mechanical Drawings section of this guide.

Four screws pass through the housing of the antenna.

Install the antenna as follows:

1. The antenna is supplied with an o-ring. Place it in the o-ring groove of the antenna base. A user-sup-

plied o-ring grease can be used to hold the o-ring in the groove during installation.

2. Pre-drill and tap the mounting holes and drill the connector clearance hole on the surface, see the

Mechanical Drawings section of this guide for details on the mounting pattern.

3. Attach the antenna to the surface using the four mounting screws supplied (use of user-supplied

thread-locking material is recommended). The o-ring compresses and creates a seal between the

surface and the antenna.

4. Remove the dust cap from the antenna’s TNC connector.

5. Attach the male TNC connector of the coaxial cable to the antenna’s TNC connector:

6. Attach the other end of the coaxial cable to the antenna input port of the receiving device, which must

provide power as detailed in the SPECIFICATIONS section of this guide. All NovAtel GNSS receivers

provide the necessary power through their antenna RF connectors.
