Connect a 5G router’s four cellular antenna inputs and GNSS input through one roof-mounted assembly with Teltonika PR1KCI49. The mobile antenna section covers 600–960 MHz and 1,400–6,000 MHz, combining linear polarisation with an omnidirectional radiation pattern and maximum gain of 4.9 dBi. Four SMA male connectors provide the mobile connections, each with 50 Ω impedance and a specified VSWR of ≤ 3.2. This combination suits installations that need multiple cellular antenna paths and satellite positioning from a single roof mounting location. Keep positioning on its own antenna path: the GNSS section covers 1,164–1,189 MHz and 1,559–1,606 MHz through a dedicated SMA male connector. It uses right-hand circular polarisation and a directional radiation pattern, with gain of 17 ± 2 dB, VSWR below 2 and 50 Ω impedance. GNSS requires a 3–5 V DC supply and draws 16 ± 3 mA. For vehicle telemetry or a location-aware IoT gateway, these separate mobile and GNSS connections let the router handle cellular communications and positioning through the same external assembly. Route the four ALS302 mobile cables and single RG174 GNSS cable from the roof to the equipment location; each cable is 3,000 mm long. Screw mounting uses an M27 nut, with a recommended 28 mm assembly hole and 3 mm mounting plane thickness. The assembly weighs 780 g and operates from -40 °C to +85 °C. IP67 and IP69K ratings apply after installation, making the completed mounting arrangement relevant to weather exposure and washdown conditions. RoHS compliance is specified.
