Connect four mobile antenna connections on a compatible 5G router through one roof-mounted assembly. Teltonika PR1KC647 combines mobile MIMO capability with four SMA male connectors, each attached to a 3,000 mm ALS302 cable. Its two frequency ranges cover 600–960 MHz and 1,400–6,000 MHz, giving engineers specific limits to compare with the router’s operating bands. Linear polarisation and an omnidirectional radiation pattern support mobile connectivity without requiring a fixed directional bearing toward a serving cellular site. Maximum antenna gain is 4.7 dBi, with 50 Ω impedance and VSWR of no more than 3.4. Install the assembly on a vehicle roof or another suitable mounting plane using its screw attachment and M27 nut. The mounting thread is M27 × 2, and the recommended assembly hole diameter is 28 mm. A recommended mounting plane thickness of 3 mm gives installers a concrete mechanical requirement when assessing the roof or mounting panel. Four cable runs allow the router to sit away from the antenna position; nominal cable length is 3,000 mm with a tolerance of ±150 mm. Each run terminates in an SMA male connector for the corresponding router antenna connection. Use the antenna in outdoor mobile and IoT installations requiring a permanent roof attachment. IP67 and IP69K ratings apply after installation, making the completed mounting arrangement part of the environmental protection requirement. The operating temperature range extends from -40 °C to +85 °C. Product weight is 701 g, and the antenna is RoHS compliant. This combination of four mobile antenna connections, dual frequency ranges and screw mounting suits installations that need multiple cellular antenna paths in one roof assembly.
