The Garmin BlueNet marine network cables offer additional cable lengths to help with installations. Additional sizes sold separately.
The short (1ft) Garmin BlueNet network cable is used to connect a Garmin BlueNet 20 switch or Garmin BlueNet 30 gateway to each other, or other Garmin BlueNet network products.
Consider purchasing the Field installable Adapter Kit for the Garmin BlueNet network if purchasing the 500-foot-long cable.
