Installation / Environmental

The dome shaped housing measures Ø 96 x H 130 mm and is manufactured with durable ASA material that can operate in extreme temperatures without any compromise to performance. The antenna base is made with aluminum alloy that feeds the dual cables through the anti-rotation screw mount. 2J7107BGF is fully IP67, IP69 and IK09 rated and gives this antenna complete resistance to water, dust, and impact, making it ideal for outdoor rugged environments. The 2J7107BGF comes with a 300 cm long LL195 cable for the TETRA/UHF connection and a LL100 cable for the GNSS connection with SMA-Male connector types. We offer a large selection of alternative connectors and cables to meet any customization needs. This antenna has been measured in a certified 3D Anechoic Chamber and tuned for optimal performance. All products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance.
