863-870 MHz 5 dBi Fiberglass Antenna Datasheet
Overview
Product Description
RAK’s 5 dBi fiberglass antenna is an outdoor, high-performance antenna, designed to withstand harsh outdoor conditions. It is specially designed for LoRa in the 863-870MHz band – EU868, IN865, and RU864.
The antenna connector is one with the antenna body - this design further increases the resistance of the antenna to external conditions.
With a length of only 480 mm, this antenna will be the best fit for your LPWAN gateway or outdoor deployed RAK Hotspot.
NOTE
This antenna is designed to be directly mounted on the enclosure of the Gateway. It is suitable for the following RAK products:
The antenna is also compatible with the following:
