Antenna Description

The #1 Heavy-Duty Low Frequency Antenna for Reliable Communication 

The heavy-duty, ground plane dependent antenna 2J7790M operates with LTE 450 technology (410-496 MHz frequency band).  Its low frequency (450 MHz) gives wider area coverage than higher frequencies, robust signal penetration, high-speed connectivity, and dependable security. Unlike typical public networks operating at higher frequencies like 900, 1800, 2100, or 2600 MHz, LTE 450, often referred to as band 31, necessitates a dedicated module. This immediately gives LTE 450 an advantage in terms of less signal congestion, leading to exceptional network performance.

For detailed antenna specifications, please see our comprehensive datasheet.

This antenna is the perfect solution for the rapidly growing demand of reliable communication. Various industries can take advantage of its many capabilities, including:

Suggested applications include: 

  • Internet of Things (IoT) In particular, LTE 450 supports CAT-M and narrowband IoT (NB-IoT) technologies, which are dedicated to IoT connectivity.
  • Machine to machine (M2M) applications
  • Logistics and Shipping
  • Industrial IoT & Monitoring
  • Smart Farming
  • Security and Surveillance
  • Mission Critical Communications
  • Transportation

The 2J7790M brings signal performance and quality in a 360-degree radiation pattern due to its omni-directional design while maintaining a maximum peak gain of ~2.8 dBi.

Installation / Environmental

This cylinder shape housing (Ø 54 x 68.2 mm) 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. 

2J7790M comes with a powerful magnetic mount that is strong enough for long-term applications but also offers the convenience of frequent relocation on any metal surface. Given the LTE 450 spectrum's recognized efficiency in remote areas and its ability to maintain strong signals even through walls and underground, it becomes the top choice for devices typically installed in basement locations below ground level.

The cable comes 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.
