electric shock.

recommended distance away from other electronics、 wiring、 or metal,
other EnGenius antennas, at least 1 foot away from metal).

•

For FCC compliance, the outdoor antenna must not be located within 8 inches

(20cm) of any person.

The higher the antenna is installed, the better the communication will be. If you

can install the antenna higher than surrounding obstructions, the
communication range will be better.
