The Digi 76000926 is a replacement or spare indoor cellular antenna for Digi equipment with SMA antenna ports. It screws directly onto the device through its SMA male connector, so no cable is needed. That makes it a tidy choice for routers and serial servers installed in offices, cabinets and control rooms where the equipment sits in usable signal. The antenna covers the 3G/4G/LTE ranges of 699–960 MHz and 1710–2690 MHz, including the low bands that matter for building penetration. It is rated at 3 dBi gain with linear polarization and 50 Ω impedance. VSWR is below 3:1 across most of the range and below 5:1 at 2500–2690 MHz. The black ABS housing measures 38 x 196 x 13.8 mm (W x H x T) and weighs 40 g. Its −40 °C to +85 °C operating range matches the temperature ratings of industrial hardware in unconditioned indoor spaces. Digi lists this antenna for the following products: - Digi IX20 Industrial 4G LTE Router - Digi Connect EZ 16/32 - Digi Connect EZ 8 - Digi Connect EZ Mini/2/4 - Digi Connect Sensor XRT-M Use one per cellular antenna port. Multi-antenna devices typically need one per port to achieve full MIMO performance.
