The Digi 76002103 is the manufacturer's replacement or spare cellular antenna for the Digi IX10 and Digi IX15. It is a linear-polarized dipole that attaches directly to the router's cellular port with an SMA male connector. There is no cable run, so it takes seconds to fit on a bench, in a cabinet or at an equipment rack. Digi lists it as one cellular antenna with an order quantity of 2, which covers a router's cellular antenna ports or keeps spares on hand. RF performance is specified across three 3G/4G/LTE frequency ranges: 698-960 MHz, 1710-2170 MHz and 2500-2700 MHz. Gain runs from 0.6 to 2.6 dBi, and impedance is 50 Ohms. VSWR is rated at 1.7:1 in the low band, 1.5:1 in the mid band and 1.3:1 in the upper band. The housing is black PC/ABS with UV-stable material. The antenna measures 170 x 18 x 10 mm (6.69 x 0.71 x 0.39 in) and weighs 25 g. Digi classifies it as an indoor antenna. Its -40 °C to 85 °C (-40 °F to 185 °F) operating range suits control cabinets, kiosks and industrial enclosures where temperatures swing well beyond office conditions. For IT and operations teams running IX10 or IX15 fleets, this is the matched Digi part. It restores a damaged or missing antenna or completes a deployment kit without guesswork about fit.
