Antenna Description

2J6901BC2F

Designed with superior accuracy and reliability for the new generation GPS applications

This high precision, low profile external antenna (2J6901BC2F) is designed for demanding GPS applications that require centimeter-level accuracy by combining Precise Point Positioning (PPP) of L1 and L2 with Real-Time Kinematic (RTK) satellite navigation. With low-power requirements, the 2J6901BC2F caters to GPS, Qzss, GLONASS, BeiDou, Galileo and SBAS standards while operating at high efficiency within 1227 MHz and 1561-1606 MHz frequencies.

Used for both receiving and transmitting applications, this active antenna is ideal for external environments where longer remote cable runs are required. This antenna is the first choice for land and hydrographic survey applications because it uses real-time error corrections while simultaneously maintaining centimeter precise position data throughput when passing through solid objects or high coverage landscapes.

Suggested applications include:

- Land Survey
- Hydrographic Survey
- Unmanned Aerial Vehicle Navigation
- Autonomous Vehicles
- Civil Aviation

Compatibility Standards

L2
-GPS(L2C), QZSS(L2C)

L1
-GPS(L1C), GLONAS(L1OF), BeiDou(B1), QZSS(L1C), Galileo(E1), SBAS (L1)

The 2J6901BC2F offers low noise figures of 1.6 db @3V, ESD 2kV protection and a high rejection pre-filter without compromising active gains of 28 dB @3V.

Installation and Durability

The 2J6901BC2F is enclosed in a waterproof and dust resistant ASA UV-stable housing that measures 80 x 74 x 25.6 mm protecting the antenna in the most extreme environmental conditions. The anti-rotation screw mount and ground plane independence allow this external antenna to be installed securely on a wide range of surfaces without restrictions. The 2J6901BC2F is delivered with a standard SMA-Male connector and a 300 cm long LL100 cable (custom options available). Please contact our highly skilled team members to assist with customization and integration needs. 2J Antennas recognizes the importance of the environment and has implemented steps to further sustainability making us fully RoHS and Reach compliant.
