Routers lose antennas - to moves, tampering, tight cabinets, and the occasional forklift - and a Wi-Fi radio running on a missing or mismatched antenna wastes the performance the router was bought for. The PR14RD35 is Teltonika's own dual-band Wi-Fi antenna for the RUTX10 and RUTX11, covering both the 2.4 GHz and 5 GHz bands the routers' concurrent dual-band radios use. As a genuine accessory it restores the exact RF configuration Teltonika certified, which keeps performance predictable and support conversations simple. UPC 4779051840342 identifies the retail unit. The Wi-Fi antenna is tuned for dual-band Wi-Fi service and terminates in a Router Wi-Fi antenna port (RP-SMA class) connector. Dual-band coverage matters: single-band replacement whips quietly cripple the 5 GHz radio. Hand-thread the antenna onto the router's Wi-Fi port and angle it vertically for the best coverage pattern. Keep one or two in the spares drawer per site - it is the cheapest fix in the Teltonika catalog for a degraded WLAN. Cloud Care Networks stocks the Teltonika PR14RD35 alongside the gateways and routers it supports, so IT and field-service teams can consolidate antennas, spares, and replacement hardware on a single order.
