Waterproof Fibreglass Antenna 860-930MHz 5.8 dBi for Helium Hotspot HNT Miner

Feature: Outdoor antenna, for LoRa antenna outdoor omnidirectional fiberglass antenna LTE outdoor long-distance receiving antenna The antenna has N-Male connector , so it can be easily connected to the and all other helium miners. The antenna can be used in any environment that requires a long-distance for LoRa connection, for agriculture, environmental monitoring, and urban monitoring Low VSWR： The VSWR of this antenna is 1.1, which is lower than other antennas (the closer the VWSR is 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 nominal 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.
