TRIMBLE BULLET GG GNSS ANTENNA
HIGH GAIN ANTENNA FOR HARSH ENVIRONMENTS
5.0V OR 3.3V, TNC OR F- TYPE CONNECTORS, RESISTS RF JAMMING
The Trimble® Bullet GG antenna provides a perfect solution for manufactures who need a fixed-site, rooftop multi-GNSS antenna. The Bullet GG supports GPS and GLONASS constellations. The antenna is also a high-quality solution for adding GNSS RF signals for marine GNSS 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. The socket accepts either a 1"-14" straight threat (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.
The Bullet GG antenna is an active GPS & GLONASS antenna with 35dB preamp (5V DC), 30dB preamp (3.3 VDC). The high-gain preamp allows the Bullet GG antenna to be used with up to 75 feet of RG-58 or RG-59 cable. The Bullet GG filtering improves impunity to other RF signals for reliable performance in hostile RF jamming environments.
For over 20 years, Trimble has sold GPS antennas renowned for their survivability in tough environments. The Bullet GG antenna is the fifth generation of the proven Bullet antenna family and offers all the reliability and performance benefits that are required for GNSS installations. In unforgiving environments, an antenna failure could be disastrous. Don't risk it. select a proven GNSS antenna – the Trimble Bullet GG antenna
RECOMMENDED CABLE & 50/75 OHM ISSUE
Trimble recommends the use of a RG59, 75-ohm cable as a low cost and readily available coaxial cable for the Bullet antenna. Extensive testing by Trimble has shown a minimal attenuation factor of less than 0.5dB (1/2dB) loss using the 75 Ohm cable with a 50 Ohm connector and antenna. The GPS frequency of 1575.42 MHz has negligible attenuation effects between the differences of equipment impedance.
Trimble recommends that the utmost consideration be given to the coaxial cable distance from the Bullet III antenna to the GPS module, including the GPS input receive level, using either 50 or 75 ohm coaxial cable. Using Trimble embedded products, allow for a minimum of 18 dB of gain at the R/F connector input of the GPS and 20 dB of gain at the R/F connector for the ThunderBolt Disciplined Clock. While the Bullet antenna will effectively perform for other vendor supplied GPS products, the correct input sensitivity level is required for optimum functionality.
The Bullet GG has a 1”-14 thread and comes with either a TNC or F-TYPE connector.
