Directional Antennas
These antennas transmit and receive radio frequency (RF) energy in a specific direction, usually from the front.
The RF energy pattern is fan-shaped, focused outward from the front of the antenna.
Important Safety Tip:
Avoid walking or working directly in front of these antennas. There is no RF energy emitted behind them, so staying behind or to the side is safer.
Omni-Directional Antennas
These antennas are typically cylindrical or rod-shaped.
They transmit RF energy in all directions, creating a 360-degree signal around the antenna.
Important Safety Tip:
Avoid walking or working at the same height or level as these antennas. RF exposure is strongest on the same horizontal plane.
