Every field tech carries a version of this part, and the PR1KS210 is Teltonika's own: a mobile LTE antenna on a magnetic base with an integrated cable and SMA termination, listed for RUT230, RUT240, and the wider RUT family. Its job is relocation - lifting the cellular element out of a drawer, panel, or basement corner and planting it on the nearest steel surface with better exposure. Because the magnet holds without hardware, it is equally at home as a permanent small-site antenna or a diagnostic tool for proving what better placement would earn. The cellular antenna is tuned for 4G LTE cellular service and terminates in a SMA male connector. Before buying boosters, move the antenna - a few meters of cable routinely beats amplification. Plant the base on steel - cabinet top, shelf bracket, machine housing - route the cable, and thread the SMA onto the router's mobile port. Watch RSRP in the router's status page while repositioning to find the sweet spot. Cloud Care Networks stocks the Teltonika PR1KS210 alongside the gateways and routers it supports, so IT and field-service teams can consolidate antennas, spares, and replacement hardware on a single order.
