Teltonika's RUTX12 and RUTX14 demand more antenna than most accessories provide - the RUTX12 runs two modems and the RUTX14 runs 4x4 MIMO, both wanting four cellular feeds. The PR1KCL28 answers with four LTE elements plus a GNSS element in a single roof-mount housing, every lead terminated SMA. On the RUTX12 the four elements split two-per-modem for dual-carrier redundancy; on the RUTX14 they run as a 4x4 set for maximum LTE throughput. Either way, one bolt-through housing replaces what would otherwise be five separate roof penetrations. The combination antenna is tuned for 4G LTE cellular and GNSS service and terminates in a SMA connector. Dual-modem RUTX12 installs get carrier redundancy from one housing - two SIMs, two networks, one antenna part. Bolt through the roof, seal, and land four cellular leads on the router's mobile ports plus GNSS on the position port. Label leads as you go; four-plus-one installs reward tidy habits. Cloud Care Networks stocks the Teltonika PR1KCL28 alongside the gateways and routers it supports, so IT and field-service teams can consolidate antennas, spares, and replacement hardware on a single order.
