Connect a compatible router's cellular antenna interface with the Teltonika PR1US450 angled compact mobile SMA antenna. Its 700–2,700 MHz frequency range, 5.0 dBi gain and linear vertical polarisation define its RF characteristics. The antenna has a 50 Ω impedance and a VSWR specification of 1.8. These values give engineers concrete criteria for matching the antenna to a cellular radio interface, alongside the connector type and the operating frequencies required by the installation. Frequency coverage remains a separate selection criterion from physical connector compatibility. Fit the antenna through its SMA male connector, which has a straight connector configuration despite the angled antenna body. This distinction matters when checking the space around a router's antenna sockets: the product's angled shape describes the antenna, while the connector specification describes the mating interface. Its compact body has stated dimensions of 50.0 × 10.5 × 17.0 mm. Those measurements help assess clearance beside adjacent connections and within equipment housings before selecting the mounting position. Use this antenna with compatible Teltonika mobile routers, including RUT230, RUT240, RUT900, RUT950, RUT955 and RUTX09. A replacement antenna installation on one of these routers is a concrete application for its mobile frequency coverage and SMA connection. Within the antenna range, this option combines an angled compact form with a straight SMA male connector and 5.0 dBi gain. Select it where those physical and RF characteristics match the router interface and available installation space.
