USER GUIDE
The GPS-702L 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. It also has excellent reception of low
elevation angle satellites (for example,
CDGPS, OmniSTAR, GPS, SBAS). The 702L can be distinguished from other GPS-700 models by its grey rim. This guide
provides the basic information you need to ins tall and begin
using your new antenna.
ADDITIONAL EQUIPMENT REQUIRED
The equipment listed below is required to set up the GPS-702L:
• 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 GPS 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 RF 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 RF reflective surfaces are within 30
m, ensure the site is as high as possible. Otherwise,
mount the antenna as low to the ground 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, add jam nuts or washers to shorten the
exposed thread, ensuring any 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.

Do not attempt to remove it.
3. Remove the dust cap from the antenna’s TNC 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 inpu t
port of the receiving device, which must provide power as

ANTENNA CARE
The GPS-702L is designed to withstand the elements, including
rain, snow , and dust. However, to ensure yo ur ante nna perfo rms
optimally, keep the radome (the top surface of the antenna)
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.

Height = Vertical phase center offset from antenna reference
point or antenna reference plane (ARP), see Table 1.
For absolute and relative offset numbers of phase center variation (PCV tables available for download), please visit the GEO++
website at www.geopp.com.
When using either of the websites mentioned above, look for the
NovAtel listing of your antenna model and its hardware revision.
Only integer hardware revisions affect the phase center offsets. For
example, the numbers given for hardware revision 2.02 are applicable to an antenna labelled H/W Rev: 2.00, 2.04, 2.12 and so on.
Table 1 shows typical absolute and relative offset numbers for
the current 702L antenna model.
