Novatel GPS-704-WB User Manual

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.
