Installation / Environmental

The elegantly designed dome-shaped housing measures Ø 96 × 90 mm and is made from industrial-grade ASA UV stable 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 screw mount is ideal for long-term installations but also ideal for temporary installations on any surface for short-term applications. This antenna combination is also available with magnetic, pole, and lightweight plastic screw mounting options.
All cables are high-quality low loss (LMR195/LMR100) cables and are connected via SMA-Male connectors.  This antenna has been tuned to a standard 300 cm cable length for optimal performance however we offer a large selection of alternative cables.
To support the health of our environment, all our products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance. Our engineers are available 24/7 to assist with any customization or antenna selection needs.
