Helium Hotspot Antenna 868MHz Fiberglass Aerial Kit For LoRa IoT HNT Miners

Feature: This series of antennas are designed for use outdoors for a long time. Highly weather-sealed fiberglass design around the copper dipole, with aluminum base and connectors. The double waterproof seal prevents water from entering. Rated to withstand wind speeds up to 215km/hr (60m/s) The operating temperature range is -40°C to 60°C. IP67 rating, resistant and highly waterproof Designed for Helium, FLARM, OGN, for LoRa and other 868Mhz applications. Suitable for the following Miners Bobcat Nebra (Indoor/Outdoor) RAK Wireless RAK2 Wireless Syncrobit Cal-Chip LongAP Sensecap Kerlink 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 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. Specification: Color: gray fiberglass antenna Frequency: 860-930MHz (EU 868MHz, US 915MHz) Feature: Fixed Wall Mount Maximum gain: 8dbi (not a fixed value) Rated Gain: 3dbi Standing wave ratio: ≤1.5 Type: for LoRa/LPWAN antenna Material: Fiberglass Impedance: 50 ohm Polarization: vertical Connector: N-type male Cable length: 1m Antenna length: 32cm Package Contents: 1 x 32cm antenna 1 x 1m RG-58 low loss coaxial cable 1 x -arrester (N-male to N-Female) 1 x bracket 1 x SMA female to RPSMA male adapter Note: Due to the difference between different monitors, the picture may not reflect the actual color of the item.
