Overview

The IS.04.B.301111 is a low-profile, permanent-mount 868MHz dome antenna designed for robust IoT and telematics applications. It provides 2.09dBi gain and features a 3-meter RG-174 cable terminated with an SMA Male connector for easy integration into outdoor or industrial enclosures.

Why Choose This Part

This antenna offers an extremely high level of environmental protection with IP67 and IP69K ratings, making it resistant to high-pressure water jets and harsh outdoor conditions. Its UV and vandal-resistant polycarbonate housing ensures longevity in public or industrial spaces, while the -21.93dB return loss indicates high electrical efficiency within the 868MHz to 870MHz band.

Applications

LPWAN Gateways
Ideal for 868MHz LoRaWAN or Sigfox base stations and gateways requiring a vandal-resistant external antenna.
Remote Utility Metering
Used in smart grid infrastructure where high durability and IP69K environmental sealing are required for long-term outdoor deployment.
Fleet Management
Low-profile design is suitable for vehicle roof mounting to provide reliable communication for asset tracking and telemetry.
Smart Cities
Supports urban infrastructure sensing, such as parking sensors or street lighting controllers, where UV resistance is critical.
