Also included is a magnetic base. 3.Compatible with RAK 2 Nebra Indoor and Bobcat 300 (915 MHz and Australia versions only). 4.You can use the included magnet base with the factory antenna of any of these miners or with the included 5.8 dbi 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. Specifications: Frequency range: 900-930 MHz Gain: 5.8 dBi VSWR
