KVH 72-0409 Mounting Bracket for M1 Antenna

M1 Mounting Bracket, you can mount the antenna with any standard stainless
antenna mount available from your local marine equipment supplier! Use this bracket with a standard threaded steel mount (1″-14 threads) to make the TracVision M1 a drop-in replacement for a Shakespeare SeaWatch or Glomex off-air antenna. Just thread the mounting nut and mounting bracket onto the antenna mount, then screw the antenna to the mounting bracket – that’s all there is to it!
