Customer Service Warranty Service Product Description Description: 3/4/5dBi for Helium Hotspot Miner Antenna+Magnetic Base 858-878MHz for LoRa/HNT Mining Machine Antenna Long Range Outdoor Network High Gain Signal Booster Kit Feature: The antenna has a Female-to-RP-SMA connector cable, so it can be easily connected to the gateway and all other for helium miners. The antenna can be used in any environment requiring long-distance for LoRa connection, agriculture, environmental monitoring, urban monitoring, etc Increase signal strength: internal copper oscillator, 3dBi / 4dbi / 5dBi gain, omnidirectional, long distance, far coverage, low standing wave ratio Durable material: outdoor all day work, anti-corrosion, waterproof, rainproof, easy to install. The radome is made of FRP and the antenna base is made of thickened aluminum, which is firm and durable and can resist strong wind. You can use the supplied suction cup base with the antenna. As the gain increases, your vertical path will decrease, allowing you to communicate with the hotspot from a longer distance, but reducing your ability to enter a closer hotspot path. Over time, your community will encounter new miners, so you may need to adjust the antenna you use to deal with the density.
