    Antenna description


    Centimeter‑Level Position Accuracy, High Precision For a New Generation of GPS Applications

    The magnetic 2J7C01MC2F is designed for high precision and centimeter-level accuracy. By combining Precise Point Positioning (PPP) of L1 and L2 with Real-Time Kinematic (RTK) satellite navigation, this antenna can match military specification accuracy. This external antenna caters to all major GNSS bands including GPS, GLONASS, BeiDou, QZSS, Galileo and SBAS (Satellite-Based Augmentation System) 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. 2J7C01MC2F is the #1 choice for land and hydrographic survey applications as it uses real-time error corrections while simultaneously maintaining centimeter precise position data, 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

    -GPS(L2C), QZSS(L2C)

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


    This high-performance antenna is designed to operate with low power consumption (48mW) and offers low noise figures of 1.6 dB @3V while implementing a high rejection pre-filter without compromising active gains of 28 dB @3V.

    Installation and Durability

    The 2J7C01MC2F is enclosed within a dome-shape ASA UV stable housing (IP67/ IP69 rated) that is waterproof, dust resistant and durable in extreme environments.  A strong magnetic mount gives this antenna the flexibility for temporary or permanent installations.  This antenna has a compact and low-profile form factor measuring only Ø 54 x 21.5 mm. Delivery includes a single standard SMA-Male connector and a 300 cm long LL100 cable. Custom cables and connectors are available upon request by contacting our expert team for any customization or antenna selection needs. 2J Antennas cares deeply about the environment and we take the necessary steps in design, manufacturing and delivery of our products without hazardous materials to meet RoHS and Reach requirements.
