Connecting the Outdoor Wireless Antenna
Grounding and power surges
The image below illustrates a typical installation scenario.
Note that the overall system can have multiple devices that are interconnected via Ethernet cables, and these
devices can each have separate connections to the AC outlet and local grounds at different points throughout the
home.
The OWA system is designed to block the surge current with potential surge paths protected with 6KV or 10KV
isolation barriers. Any attempt to add grounds or grounded protectors to the system may actually weakens the
surge resistance.
The PoE cable should be physically separated by at least three feet from any other cable, such as power cables or
lightning down-conductors. This separation will help avoid unwanted coupling of surge transients onto the PoE
cable.
