    • This is an indoor antenna and not rated for outdoor use.

    • We recommend placing this inside near a window, or in a more optimal place for sending and receiving than where your miner currently is.

    • This is a rigid solid antenna with no elbow bend point for best performance.

    • We recommend using this antenna with the included magnet base for maximum performance.
