CrossCheck CDPD Mobile Unit Manual
Maintain a separation of at least 46 cm (or approximately 18 in.)
between the cellular (or other) and GPS antennas (as illustrated in
Figure 2.12).
Figure 2.12 Distance Between Antenna Locations
In general, the greater the separation, the less chance of interference.
For permanent antenna installations, choose a location with access
both above and below the antenna mounting surface. This access is
required for installing fasteners and for routing the antenna cable.
Cellular phone dealers and installers are experts on cellular antenna
placement. For some installations, the installer may substitute a glass-
mount antenna for the antenna supplied by Trimble. Other antennas
are acceptable as long as they conform to the requirements listed in
Appendix A.
Trimble offers two cellular antenna options for the
CrossCheck CDPD. The Magnetic Antenna is recommended for
temporary installations. A Bulkhead Antenna is recommended for
permanent, surface-mount installations.
