Antenna Description


Heavy Duty 3-in-1 Combination Antenna with Exceptional High Performance

2J7041MGFa is a high gain, high performance, heavy duty, wide band 3-in-1 antenna designed for Cellular, LTE and GNSS applications. This multi-function antenna comes with a super strong magnetic mount and is ideal for automotive, industrial equipment and transportation applications where permanent screw mounting is not an option. 

The dual Cellular / LTE cable (#1 & #2) is dedicated to voice and data devices that operate within 4G LTE, FirstNet, LPWA, NB-IoT, Cat-X-Mx-NBx, 3G and 2G standards. This antenna offers high gains with high efficiency across 698 MHz – 2700 MHz frequency bands and is backwards compatible with existing LTE networks. By adding dual cellular capabilities, the antenna can consistently search and pair the strongest signal to assure uninterrupted connectivity regardless of the location and angle. 

Single cable (#3) GNSS antenna is designed with navigational precision for automotive and transportation applications that operate within GPS, QZSS, Galileo and Glonass standards. With hemispherical radiation pattern, RHCP and saw filter, this antenna offers a high active gain with excellent efficiency across 1575.42 MHz and 1598-1606 MHz frequencies. 

For detailed antenna specifications, please see our comprehensive data sheet.


Typical applications

- Telematics
- Cellular Mobile and Internet
- Industrial Machinery and Automation
- Automobile / Transportation
- Critical Communication Services
- Consumer Electronics and Smart Home / Office
- Outdoor building and roofs



Installation / Environmental

The dome shaped antenna housing measures Ø 96 × 102 mm and is made from industrial grade ASA material with an aluminum alloy base. With full IP67, IP69 and IK09 certification, this antenna is fully waterproof and resistant to dust, high temperatures and impact ideal for outdoor applications. 

The powerful magnetic mount is strong enough for long term installations but also ideal for temporary installations on metal surfaces for short term applications on the go. The antenna base includes a thin, soft rubber layer to protect metal surfaces from scratches during installation or removal. This antenna combination is also available with screw, pole and lightweight plastic screw mounting options. 

All cables are high quality low loss (LL195/LL100) cables and connected via SMA-Male connectors.  This antenna has been tuned to standard 300 cm cable length for optimal performance however we offer a large selection of alternative cables and. Our 2J Antennas engineers are available 24/7 to assist with any customization or antenna selection needs. 

To support the health of our environment, all our products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance.
