Trimble Bullet 720 GNSS Antenna
Introduction

Trimble's Bullet 720 is a ruggedized weatherproof dual-band (L1 & L5) multi-GNSS active antenna. It is designed with a high out-of-band rejection filter and a built-in LNA to compensate for feedline losses and provide improved performance in harsh GNSS environments.

Additionally, Bullet 720 offers the benefits of using the higher power L5 signals (twice as much power as L1). With its greater bandwidth and advanced signal design, it lowers the risk of interference and improves multi-path protection. The dual-band capability of the Bullet 720 allows GNSS receivers to compensate for ionosphere errors allowing the reduction of the timing error under clear skies to a few nanoseconds.

When used with a dual-band GNSS receiver, such as Trimble's RES720 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 applications.

MULTI-GNSS

The Bullet 720 is an active Antenna that supports GPS L1 & L5, Galileo E1 & E5, Beidou B1 & B2C, GLONASS G1 and IRNSS bands.

ANTI-JAMMING

The Bullet 720 antenna 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.

HIGH OUT-OF-BAND (OOB) REJECTION

Bullet 720 provides class-leading out-of-band rejection characteristics of >75dB for L1 and > 65dB for L5 band. It provides significant improvements in performance and robustness in environments with high interference and multipath.

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 of equipment impedance.

Trimble recommends that the utmost consideration be given to the coaxial cable distance from the Bullet 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 III antenna will effectively perform for other vendor-supplied GPS products, the correct input sensitivity level is required for optimum functionality.

MOUNTING

The Bullet 720 comes with a mounting nut and is available with an optional mount. The antenna has a standard N-TYPE jack connector.
