Whatever the environment— wet, cold, sunny, hot, harsh RF
jamming—Trimble’s Bullet™ III
GPS antenna can take it, year
after year. Designed primarily
for stationary applications, the
Bullet III antenna provides a
perfect solution for manufacturers
who need a fixed-site, rooftop
GPS antenna. This antenna
is also a high-quality solution
for adding GPS RF signals to
marine GPS navigation systems. |
| The antenna is housed in
completely waterproof packaging
designed to withstand
exposure to shock, excessive
vibration, extreme temperatures,
rain, snow and sunlight.
The enclosure is a textured
off-white color and is both
weatherproof and waterproof. |
| The dome is all plastic, and
the threaded socket in the base
of the antenna is corrosion
resistant. The threaded socket
accepts either a 1"-14" straight
thread (typical marine antenna
mount) or a 3/4" pipe thread. |
| The F-type or TNC antenna
connector is located inside the
threaded socket, which allows the
antenna cable to be routed inside
the pole and protects the
cable connection for added
reliability. |
| The Bullet III antenna is an
active GPS antenna with 35-dB
preamp and dual bandpass
filters. The high-gain preamp
allows the Bullet III to be used
with up to 75 feet of RG-59
cable. The bandpass filters
improve immunity to other
RF signals for reliable performance
in hostile RF jamming
environments. |
For over 15 years, Trimble has
been producing GPS antennas
renowned for their survivability
in tough environments. The
Bullet III is the fourth generation
of the proven Bullet antenna
family (more than 40,000 delivered)
and offers all the reliability
and performance benefits that
this exceptional field experience
provides. |
| In unforgiving environments,
an antenna failure could be
disastrous. Don’t risk it. Select
a proven, stress-tested, GPS
antenna—the Trimble Bullet III
GPS antenna. |
