Since a person above deck may not know which direction the antenna is pointing, you should always observe the minimum safe distance to prevent RF radiation exposure. Within the antenna’s elevation range, the minimum safe distance is 32 feet (10 m). No hazard exists directly below the antenna.

NOTE: You can set up no-transmit zones to inhibit transmissions within areas frequented by passengers and/or crew. See Establishing No-Transmit Zones for details.
