¶ General Description
The Delta 41 is a multi-band, direct-connect antenna for cellular and long-range LPWAN applications. It supports 2G, 3G, 4G, LTE-M, NB-IoT and 868/915 MHz ISM applications.
Offering 3 dBi gain and 71% radiation efficiency, its broad compatibility makes it a versatile choice for low-power IoT deployments, including remote monitoring, smart metering and industrial telemetry.
The flat ABS body connects directly through an SMA interface, while the 90° hinged design allows the antenna to be positioned for the best signal reception. Its omnidirectional radiation pattern and adjustable design provide flexible installation without requiring a separate mounting arrangement.
