TracNet Coastal Mounting BracketYou 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 TracNet Coastal or TracNet Coastal Pro 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!
