GPS-704-WB
GM-14915141 Rev 1 April 2015
USER GUIDE
The GPS-704-WB is an active antenna that can receive signals from GPS, GLONASS, BeiDou and Galileo
satellites as well as L-Band signals. It is designed to operate at the following frequencies:
• GPS L1 (1575.42 MHz), GPS L2 (1227.60 MHz) and GPS L5 (1176.5 MHz)
• GLONASS L1 (1593 - 1609 MHz), GLONASS L2 (1238 - 1254 MHz) and GLONASS L3 (1202 MHz)
• Galileo E1 (1575.42 MHz), Galileo E5a and E5b (1164 - 1215 MHz) and Galileo E6 (1260 - 1300 MHz)
• BeiDou B1 (1561 MHz), BeiDou B2 (1207.14 MHz) and BeiDou B3 (1268.52 MHz)
• L-Band (1525 - 1560 MHz)
This guide provides the basic information you need to install and begin using your new antenna.
ADDITIONAL EQUIPMENT REQUIRED
The equipment listed below is required to set up a GPS-704-WB 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)
• A 1" open-end wrench
• Coaxial cable with a male TNC connector
• A device with an antenna input port that both receives the RF signal and provides 4.5 - 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.

2
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. Using a wrench, tighten the adapter to the mount.
3. Remove the dust cap from the antenna’s connector.
4. Attach the male 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.
ANTENNA CARE
The GPS-704-WB is 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.

The metal adapter on the bottom of the antenna is fixed in place. Do not attempt to remove it.
