GNSS-800 Series
GM-14915147 Rev 1 February 2017
USER GUIDE
The GNSS-800 Series of antennas are active antennas designed to operate at a variety of frequencies
depending on the model selected.
This guide provides the basic information you need to install and begin using your new antenna. Refer to
the individual model Product Sheet for detailed specifications (www.novatel.com/products/gnss-antennas/
vexxis-series-antennas/vexxis-gnss-800-series-antennas/).
ADDITIONAL EQUIPMENT REQUIRED
The equipment listed below is required to set up a GNSS-800 Series antenna:
• A mount, such as a range pole, tribrach or tripod, 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 TNC connector
• A device with an antenna input port that both receives the RF signal and provides +3.8 to +18.0 VDC to
the antenna. (All NovAtel GNSS receivers provide the necessary power through their antenna RF
connectors.)
SITE SELECTION GUIDELINES
Before installing the antenna, select a site that as closely as possible meets the following conditions for
optimal performance:
• An unobstructed 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 multipath 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.

INSTALLING THE ANTENNA
After a site has been selected, install the antenna as follows.
1. Verify that the thread on the mount does not extend more than 7/8" (22 mm) to ensure the plastic
inside the antenna receptacle is not damaged when the mount is inserted. If it extends further than 7/8"
(22 mm), add two jam nuts to shorten the exposed thread, ensuring the nuts are well-tightened.
2. Align the mount thread with the metal adapter on the bottom of the antenna and rotate the antenna
clockwise until it is securely screwed to the mount.
3. Remove the dust cap from the antenna’s connector.
4. Attach the TNC connector of the coaxial cable to the antenna’s TNC connector.
5. Attach the other end of the coaxial cable to the antenna input port of the receiving device.
The receiving device 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.
The metal adapter on the bottom of the antenna is fixed in place. Do not attempt to remove it.

ANTENNA CARE
The GNSS-800 Series are designed to withstand the elements, including rain, snow and dust. However, to
ensure your antenna performs optimally, keep the radome (the top surface of the antenna) clean and brush
off any ice and snow. In addition, ensure the connector remains clean and dry and replace the dust cap
when a cable is not connected.

WEEE
If you purchased a GNSS-800 Series antennas in Europe, return it to your dealer or supplier at the end of
its life. The objectives of the European Community's environment policy are, in particular, to preserve,
protect and improve the quality of the environment, protect human health and utilise natural resources
prudently and rationally. Sustainable development advocates the reduction of wasteful consumption of
natural resources and the prevention of pollution. Waste electrical and electronic equipment (WEEE) is a
regulated area. Where the generation of waste cannot be avoided, it should be reused or recovered for its
material or energy. WEEE products may be recognized by their wheeled bin label ( ).
