2J7041MGFa 4G/LTE, GNSS magnetic mount Antenna Medusa 3-in-1 SMA-M 300cm

This heavy-duty 3-in-1 antenna delivers high gain and exceptional performance for cellular LTE and GNSS applications. Designed for demanding environments, it features a robust magnetic mount ideal for automotive, industrial, and transportation uses where permanent mounting is not possible. The dual cellular/LTE MIMO connections ensure reliable voice and data connectivity across 4G, 3G, and 2G networks, while the dedicated GNSS connection provides precise navigation with high active gain. The antenna is ground plane independent, waterproof, and impact-resistant, making it suitable for both temporary and long-term outdoor installations.

• High gain and efficiency across 698–2700 MHz for cellular/LTE
• Active GNSS with pre-filter and 28 dB gain for accurate positioning
• IP67, IP69, and IK09 certified for harsh environments
• Ideal for automotive, industrial, and critical communication applications

Connector & Cable

• Connector Type: SMA-Male
• Cable Length: 300cm
• Cable Type: LL195/LL100

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