Trimble bullet III Specifications

JAM-RESISTANT ACTIVE GPS ANTENNA
NOW AVAILABLE FOR USE WITH 3.3 V DC
AND 5 V DC APPLICATIONS

Whatever the environment—the

Trimble® Bullet™ III GPS antenna

will perform, year after year. 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 for marine

GPS navigation systems.

Put it anywhere

The antenna is housed in

weatherproof packaging designed to

withstand exposure to shock, excessive

vibration, extreme temperatures, rain,

snow and sunlight.

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 a mounting pole

and protects the cable connection for

added reliability.

Strong performance

The Bullet III antenna is an active GPS

antenna with 35 dB preamp (5 V DC),

30 dB preamp (3.3 V DC). The high-

gain preamp allows the Bullet III

antenna to be used with up to 75 feet

of RG-59 cable. The Bullet III filtering

improves immunity to other RF signals

for reliable performance in hostile RF

jamming environments.

Proven reliability

For over 15 years, Trimble has sold

GPS antennas renowned for their

survivability in tough environments.

The Bullet III antenna is the fourth

generation of the proven Bullet

antenna family and offers all the

reliability and performance benefits

that are required for GPS installations.

In unforgiving environments, an

antenna failure could be disastrous.

Don’t risk it. Select a proven GPS

antenna—the Trimble Bullet III GPS

antenna.
