¶ General Description
The Mike 2A is a half-wave magnetic-mount whip antenna engineered for reliable long-range sub-GHz wireless communications. Its flexible radiating element provides dependable omnidirectional coverage, while the magnetic base enables rapid installation on metal surfaces without permanent fixing.
Designed for LoRaWAN, proprietary LPWAN and other sub-GHz wireless technologies operating in the 868 MHz and 915 MHz ISM bands, the Mike 2A is ideal for smart metering, telemetry, remote monitoring, asset tracking and industrial IoT systems.
Supplied with either RG174 or low-loss LMR100 cable and SMA Male or FME Female connectors, the Mike 2A integrates easily into a wide range of applications, including vehicles, industrial equipment, control cabinets and other metal surfaces.
