Connect a compatible mobile radio to an adhesive-mounted antenna covering 824–960 MHz and 1,710–2,170 MHz. Teltonika PR1AS420 combines linear polarisation, 2.0 dBi gain and 50 Ω impedance with an SMA male connector. Its specified VSWR is 2.0. These parameters make frequency coverage and connector matching the starting points for selection: the radio must operate within these ranges and accept the antenna's connector. The two coverage windows define this antenna's RF fit more precisely than a general mobile-antenna label, particularly when checking a modem's operating bands. Route the attached 3,000 mm RG174 cable from the radio to an available mounting surface, then secure the antenna using its adhesive mounting method. The cable provides physical separation between the equipment connection and antenna position, useful when the radio sits inside a cabinet or behind installed equipment. The antenna body measures 115.6 ±0.2 mm long and 21.7 ±0.2 mm wide, with a thickness of 5.8 mm. That narrow, flat profile suits installations where mounting clearance matters and a projecting antenna would occupy more space. Match the installation environment to the antenna's −40 °C to +85 °C operating temperature range and 95% maximum operating relative humidity. Its IP50 rating provides a defined enclosure protection level without a water-protection rating, so exposed wet locations require suitable protection. RoHS compliance is specified. Within an antenna selection, this version combines adhesive attachment, a fixed cable length and an SMA male termination; those physical choices matter alongside frequency coverage when replacing an antenna or integrating a mobile connection into existing equipment.
