GPS-534 and GPS-534-C

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.

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.
