Helium Hotspot Miner 3/5/6 dBi Indoor Antenna & Magnet Base for RAK Nebra Bobcat.

This is an indoor omni-directional antenna with 3/5/6 dBi gain. Also included is a heavy duty magnetic base that measures 2.5 inches in diameter and weighs 9 ounces

Compatible with RAK 2, Nebra Indoor, and Bobcat 300 (868 MHz ).

You can use the included magnet base with the factory antenna of any of these miners, or with the included antenna. As gain increases, your vertical path will decrease, allowing you to communicate with hotspots from a greater distance but reducing your ability to be in the path of closer hotspots. As your community experiences new miners over time, it may be necessary to adjust what antenna you are using to deal with the density.
