Feature: 1.For LoRa antenna that can be used indoors and outdoors Industrial Grade Construction Durable Fiberglass Radome Excellent waterproof performance and high temperature resistance. 2.Compatible with HNT RAK Helium Hotspot Miner V2 V1 Bobcat Miner 300 syncrob it Dragino LPS8 MatchX M2 Pro Longfi LoRaWAN 3.At the same time we use KSR200 coaxial extension cable This is a high-value cable with ultra-low loss performance. 4.If it is used outdoors we recommend that you install it in an open place if it is used indoors we recommend placing this inside near-window. If there is no change in the signal when using this antenna for the first time please turn off the power of your device then plug in the antenna and then turn on the power again. Low VSWR： The VSWR of this antenna is 1.1 which is lower than other similar antennas (the closer the VWSR is to 1 the smaller the reflection and the better the match of the antenna ) How to choose dBi？ Lower dBI: Great performance on uneven terrains or areas with a high hotspot density. Higher dBI: Great performance on flat terrain and low hotspot density. Middle dBI: Perfect for those eniorments that fall in between the other enviorments described above. What is Rated gain and maximum gain? Rated gain refers to the stable value that the antenna can achieve under normal circumstances and the maximum gain refers to the maximum value that can be achieved under the lowest loss and the best environment but this value is not a fixed value and the gain is often fluctuating.
