The GNSS-750 is an active antenna designed to receive signals from the GPS, Galileo and GLONASS 
satellites as well as L-Band signals. This antenna is designed to operate for GPS L1/L2/L2C/L5, 
GLONASS L1/L2/L3 and L-Band frequency bands. The GNSS-750 is also designed to operate for Galileo 
L1/E5a/E5b and E6 frequency bands and receives Compass B1/B2/B3. This guide provides the basic 
information you need to install and begin using your new antenna.

The following equipment is required to set up the GNSS-750:

•

A sturdy pillar or mount with a 5/8" x 11 thread that extends between 3/8" and 7/8" (9 mm and 22 mm)

•

Coaxial cable with a male N connector

•

A device with an antenna input port that both receives the RF signal and provides 3.3 to 12.0 VDC to the 

antenna

Additional available accessories include the following:

•

A radome (NovAtel part number 01018195)

For optimal performance, select a site that meets the following conditions before installing:

•

An unobstructed as possible line-of-sight from horizon to horizon and at all bearings and elevation angles.

•

As far as possible from reflective objects, especially those that are above the antenna and any water bodies, 

which can be a strong source of multi-path reflections.

•

If obstructions and reflective surfaces are within 30 m, ensure the site is as high as possible. Otherwise, 
mount the antenna as low as possible.

Most NovAtel GNSS receivers provide the necessary power through their antenna RF connectors. Check 
the applicable receiver user manual for details.
