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.
