Introduction

The Bullet 360T and 360F are ruggedized weatherproof multi-GNSS antennas. The products support GPS, Galileo, Beidou and GLONASS constellations.

When used with a GNSS receiver, such as Trimble's RES360 module, the system offers unparalleled accuracy to meet the stringent synchronization needs of the next-generation networks in various industry verticals including 5G X-Haul, Smart Grid, Data Center, SATCOM, Calibration Services and Industrial Automation.

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 is 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 (Bullet 360F) or TNC (Bullet 360T) 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.

DESIGNED FOR URBAN ENVIRONMENT

The Bullet 360T and 360F active antennas are designed for long cable runs and noisy RF environments. In challenging urban RF environments, the high antenna gain will significantly improve the performance of the GNSS receiver.

ANTI-JAMMING

The Bullet 360T and 360F antennas protects GNSS receivers from interference and intentional jamming. The filtering apparatus implemented in the antenna improves immunity to other RF signals for reliable performance in hostile RF jamming environments.

PROVEN RELIABILITY

For over 25 years, Trimble has sold GNSS antennas renowned for their survivability in tough environments. The Bullet 360T antenna is the fifth generation of the proven Bullet antenna family and offers all the reliability and performance benefits that are required for mission-critical installations. In unforgiving environments, an antenna failure could be disastrous. Don’t risk it. Select a proven GNSS antenna – the Trimble Bullet 360T antenna.

RECOMMENDED CABLE & 50/75 OHM ISSUE

Trimble recommends the use of an 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 in 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.
