Antenna Description

Heavy-Duty 2-in-1 Antenna for Reliable Communication and Precise Navigation

2J7741BGF is a heavy-duty wide-band 2-in-1 combination antenna designed to work with 4G LTE and GNSS technologies such as GPS, Glonass, Galileo and QZSS. This antenna offers low power consumption and low noise for better quality, connectivity and reliability with increased data throughput. This antenna is the perfect solution for the rapidly growing demand for reliable communication and precise navigation for global connectivity.

Cable 1 is dedicated to 4G LTE/3G/2G cellular voice and data communication with high quality and speed. With an omni-directional radiation pattern, this antenna provides 360-degree signal strength while operating within 698 and 2700 MHz frequencies and offering 4.3 dBi 4G LTE peak gain. This solution is backward compatible with existing LTE cellular networks, 3G and 2G. 

Cable 2 is dedicated for GNSS navigation applications that operate within the GPS, QZSS, Galileo and Glonass standards. This active GNSS antenna is designed with a hemispherical radiation pattern for 1575 MHz and 1602 MHz bands and offers precise and reliable navigational positioning to urban or rural areas without interruptions. The 2J7741BGF features RHCP (right-hand circular polarization) and a high rejection SAW pre-filter, protecting the signal from unnecessary interference and noise. It operates with an active gain of 28 dB with uninterrupted connectivity.

Suggested applications include:

  • Remote Monitoring 
  • Gateways and Routers 
  • HD Video over LTE
  • Tracking and Mapping
  • Automobile / Transportation
  • Autonomous Vehicle and Machinery
  • First Responder and Emergency Services 
  • GPS-Enabled IoT Applications

Installation / Environmental

This cylinder shape housing is manufactured with high-quality ASA material and IP67/ IP69 and IK09 compliant design making this antenna fully waterproof and resistant to high temperatures, dust, and impact. The antenna base is manufactured with Zamak, a material known for excellent damping capacity and vibration attenuation. This is a ground plane dependent antenna with dimensions of Ø 60 x 69 mm and screw mounting with an anti-rotation mechanism which allows easy permanent or temporary installation. Both Cable 1 and Cable 2 come with standard SMA-Male connector and 300 cm long LL100 (Low Loss coaxial) known for good return loss, insertion loss and amplitude stability. All connectors and cables are fully customizable. All our products are manufactured without any hazardous material and are fully REACH and RoHS compliant.
