GPS-534 and GPS-534-C

USER GUIDE

The GPS-534 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. The GPS-534-C version is aircraft certified for navigation. This guide provides

the basic information you need to install and begin using your new 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 GPS-534. (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 that is connected to the unit's TNC female connector.

The antenna can be 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.The antenna is supplied with an o-ring. Place it in the o-ring groove of the antenna base.

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

2.Pre-drill the mounting holes and the connector hole on the

surface, see the Mechanical Drawings section of this guide for details on the ARINC-743 mounting pattern.

3.Attach the antenna to the surface using the four mounting screws supplied. The o-ring compresses and creates a seal between the surface and the antenna.

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 GPS receivers provide the necessary power through their antenna RF connectors.

The graphic above shows examples of where the 534 antenna may be placed on an aircraft or vehicle (not to scale).

ANTENNA CARE

The GPS-534 is designed to withstand the elements, including rain, snow, and dust. However, to ensure your antenna performs optimally, keep the radome clean and brush off any ice and snow. In addition, ensure the TNC connector remains clean and dry and replace the dust cap when a cable is not connected.
